How to factorise y^4-10y^3+5y^2+100y+100=0 ?

Consider two random variables x and y. x can assume values 0 and 1 with some unknown

probabilities. Also y can assume values 2 and 3 with probabilities 0.4 and 0.6 respectively. We also know

that Prob[x=0|y = 2] = 0.5 and Prob[x =0|y = 3] = 0.8, the probabilities are conditional probabilities. Now

suppose we observe the value of x to be 0 and based on this observation we predict the value of y to be

3, what is the probability that our prediction is correct?

Q.

 Ayesha started running from one end of a straight road at 5 a.m. Bhumika, standing at the other end of the road, started running towards Ayesha at 6 a.m. and met Ayesha for the first time at point P on the road. They continued running till they reached the opposite ends. Immediately after reaching their respective ends, they turned back towards their starting points and coincidently met again at the same point P. If they met for the first time at 7 a.m., then what was the ratio of the speed of Ayesha to that of Bhumika?
