Q1) The odds against X solving a problem is 8:6 and odd in favour of Y solving a problem is 14:16.
What is the probability that the problem will be solved if they both try.

Q2) Suppose, X has the pdf:
f(x) = 3x^2 , 0<x<1.
      = 0 otherwise.

Consider a random rectangle whose sides are "x" and "1-x". Determine the expected value of the area of rectangle.
