Find some conditional probabilities. Choose a point at random in the square with sides 0 # x # 1 and 0 # y # 1. This means that the probability that the point falls in any region within the square is the area of that region. Let X be the x coordinate and Y the y coordinate of the point chosen. Find the conditional probability P(Y , 1/3 u Y . X). (Hint: Sketch the square and the events Y , 1/3 and Y . X.)
