Your instructor is playing 5 rounds of fetch with his dog Ruby. About 25% of the time Ruby gets distracted and decides to not bring the ball back, and about 15% of the time Ruby catches the ball before it bounces. Let X and Y represent the number of times the ball is returned or caught, respectively. - What are the distributions of X and Y ? - Find P ( X > 3 ) and P ( 1 < Y < 5 ) . - What are the mean and standard deviation of X and Y ?.
