Let X denote the reaction time, in seconds, to a certain stimulus and Y denote the temperature (F) at which a certain reaction starts to take place. Suppose that the two random variables X and Y have a joint density function

f(x,y)= y, 0 <= x <= 2 and 0 <=y<=1

0, otherwise

Find:

a) P(X^2 + Y^2 <=1)

b) P(X<= squt(Y))
