If a real number x is chosen at random in the interval [0, 3] and a real number y is chosen at random in the interval [0, 4 ,] what is the probability that x<y? Here's what I got - I'm hoping someone can tell me if this is a valid argument. P(x<y) = P(y>3) + P(y<3 and x<y|y<3) = 1/4 + (3/4)(1/2) = 5/8. I know 5/8 is the correct answer. Is this the correct method to get there?...
