Question 2 (variant of question 1)

A digit is drawn from digits 0 to 9 (inclusive), followed by another draw of digit. What is the probability that the product of these 2 digits is an even number when
(i) Second digit cannot be same as first digit
(ii) Second digit can be same as first digit.

Too tough for me to handle these questions. Can someone please help me with them


Regarding your 2nd Question, here is my approach:
For (i) - Second digit cannot be same as first
Total number of ways to draw 2 digits one after the other = 10 x 9 = 90.

If first digit is even, then for product to be even, 2nd digit can be either even or odd.
Therefore, no. of possible ways = 4 (no. of even digits) x 8 (excluding 0 and the one already selected) = 32
If first digit is odd, then for product to be even, 2nd digit must be even.
no. of possible ways = 5 (no. of odd digits) x 4 (no. of even digits) = 20
Therefore, total ways = 32+20=52
Probabilty = 52/90 = 26/45
----
For (ii) - Second digit can be same as first

Total number of ways to draw 2 digits one after the other = 10x10 = 100.
If first digit is even, then for product to be even, 2nd digit can be either even or odd.
Therefore, no. of possible ways = 4 (no. of even digits) x 9 (excluding 0) = 36.

If first digit is odd, then for product to be even, 2nd digit must be even.
no. of possible ways = 5 (no. of odd digits) x 4 (no. of even digits) = 20
Therefore, total ways = 36+20 = 56
Probabilty = 56/100 = 14/25

Hope these are correct answers...
Cheers!

American productivity is declining in relation to Europes; the energy expended per unit of production in the United States is as much as twice that expended in West Germany.

(A) as much as twice that expended in West Germany -CORRECT
(B) as much as twice that of West Germanys expenditure- that refers to energy expended per unit of production, So the entire meaning becomes wonky in this sentence.
(C) up to two times of West Germanys expenditure-makes the comparison to the whole expenditure-weird
(D) up to two times what West Germans expended- we are talking on countries, not the ppl
(E) up to double the West German expenditure- same as D



Hence A

(A) can, it is hoped, provide enough power to set
(B) it is hoped, can provide enough power that will set- that=> wrong referent
(C) hopefully can provide enough power, this will set-Hopefully & Hopeful are wrong 9 of 10 times ;)
(D) is hopeful to set- same as C

The Correct Idiom is Acclaimed as , NOT acclaimed to be .

(C) Martha Grahams acclaim is as - out- 's is wrongly used
(D) Martha Grahams acclaim to be-out- worng idiom
(E) Martha Grahams acclaim was in being-out - Passive

What is the Correct answer ???

PGiets, tell me one thing, i have heard a lot about 'bold Face' Questions. Is the question below an example of a bold face?
Also help me with this problem. Thanks :)


Consumer advocate: it is generally true, at least in this state, that lawyers who advertise a specific service
charge less for that service than lawyers who do not advertise. It is also true that each time restrictions on the
advertising of legal services have been eliminated, the number of lawyers advertising their services has
increased and legal costs to consumers have declined in consequence. However, eliminating the state
requirement that legal advertisements must specify fees for specific services would almost certainly increase
rather than further reduce consumer's legal costs. Lawyers would no longer have an incentive to lower their fees
when they begin advertising and if no longer required to specify fee arrangements, many lawyers who now
advertise would increase their fees.
In the consumer advocate's argument, the two portions in boldface play which of the following roles?
(A) The first is a generalization that the consumer advocate accepts as true; the second is presented as a
consequence that follows from the truth of that generalization.
(B) The first is a pattern of cause and effect that the consumer advocate argues will be repeated in the case at
issue; the second acknowledges a circumstance in which that pattern would not hold.
(C) The first is pattern of cause and effect that the consumer advocate predicts will not hold in the case at issue;
the second offers a consideration in support of that prediction.
(D) The first is evidence that the consumer advocate offers in support of a certain prediction; the second is that
prediction.
(E) The first acknowledges a consideration that weighs against the main position that the consumer advocate
defends; the second is that position.

As U.S. nuclear attack submarines prowl their familiar haunts deep within the oceans of the world these days, they increasingly are engaged in missions far different from the tasks for which they were built and for which their crews were trained over the last forty years.

(A) they increasingly are engaged in missions far different from the tasks for which they were built
(B) the missions they increasingly engage in are far different than the tasks they were built for
(C) they engage increasingly in missions that differ significantly from the tasks they were built for
(D) the missions they engage in are increasingly different than the tasks for which they were built
(E) they increasingly engage in missions far different than the tasks for which they were built

Here is my try: answer D

As U.S. nuclear attack submarines prowl their familiar haunts deep within the oceans of the world these days, they increasingly are engaged in missions far different from the tasks for which they were built and for which their crews were trained over the last forty years.

(A) they increasingly are engaged in missions far different from the tasks for which they were built - First part talks about a task/mission. This sentence doesn't seem to connect directly to the first one. Instead of a comma, a semi-colon would have been better.

(B) the missions they increasingly engage in are far different than the tasks they were built for - Although "the missions" is used here, for in this sentence not // with for in "for which their crews..."

(C) they engage increasingly in missions that differ significantly from the tasks they were built for - Same as A.

(D) the missions they engage in are increasingly different than the tasks for which they were built - Correct Answer. Second part "...and for which their crews were trained..." is // to "...for which they were built...".


(E) they increasingly engage in missions far different than the tasks for which they were built - Same as A

IMHO, the answer must be B. What the sentence says is: Kwame Nkrumah is already settled in Gharla and he has invited W. E. B. Du Bois for something...not mentioned here.

(A) At the invitation of - invitation of somthing that is inanimate (like his/her wedding) and not of a person.

(B) When he was invited by - ties correctly with invited by person and then use of settled, matches the tense.

(C) An invitation coming from - ruled out todally...very awkward const.

(D) An invitation that came from - came from someone, ok. But must have and instead of comma.

(E) After having an invitation by - by incorrectly used.
