What is the probability of finding exactly 33 multiples of 3 when 100 consecutive natural nos are selected?
1. 1/3
2. 2/3
3. 1
4. none of these

@surajmenonv said:even i am thinking the same thing.....if all the interior angles are equal...doesnt it make it a regular polygon (octagon) per se??????????? how can the sides NOT be equal.....@sowmyanarayanan pls confirm wether question is correct or not !
the lengths can vary..
have a look at this..
@catter2011 said:Puy.. how the sides vary for a regular octagon.. with angles equal ?
and equal angle doesn't necessarily mean regular polygon. on a polygon with equal sides and angle is regular
@sowmyanarayanan said:Each angle of an octagon is 135 and the sides are alternatively 2 and _/2. Find the area of the octagon.

2/3
Ditto

Is it 1?
@pavimai hey senior answere is 1/3.........every 100 consicutive number will have 33 multiples of 3 so
33/100=approx 1/3
@pavimai said:its 1..between 1-100 there will always be 33 multiples of 3
nope. it is 2/3
coz consider
1-100 => 33 multiples
2-101 => 33 multiples
3-102 => 34 multiples
so 2 out of 3 instances

@krum @pavimai @soumitrabengeri hey guys if u on fb please like this group http://www.facebook.com/groups/265906806845635/ its for malala yousufzai

its not given first 100 natural numbers, what about 6-105, there are 34 multiples of 3 here
In how many ways four letters of word STARTS be arranged?
@krum said:its not given first 100 natural numbers, what about 6-105, there are 34 multiples of 3 here
on removin "exactly" it mst be 1.. for exactly.. it shall be a universal case n 6/9 cases qualify.. that be 2/3.

Pardon me if i am wrong..but it all depends on the selections doesn't it?
If i select consecutive numbers between 3-102,6-105 and 9-108 then the prob = 0
Similarly if i select 1-100,2-200,4-400 then i will have exactly 33..then prob = 1
In the same way the prob can be 1/3 as well as 2/3
It all depends on which series of consecutive numbers you select. isn't it?
