Chapter 8.2, Problem 4MS

Rubber duckies. A game at a carnival has 75 rubber ducks floating in water. The ducks are numbered 1 to 75, with the numbers written on their under- sides so they can’t be seen. To play, you select a duck and see what number it has. If the number is less than 60, you win a consolation prize. If the number is at least 60 but less than or equal to 70, you win a stuffed duck. If the numb er is greater than 70 you win a giant, stuffed banana. What is the probabili ty you win a stuffed duck? What is the probability you don’t win a duck or a banana?
