LIST THE VARIABLES OF THE FOLLOWING PROBLEM

A survey found that 25% of pet owners had their pets bathed professionally rather than do it themselves. If 18 pet owners are randomly selected, find the probability that exactly 5 people have their pets bathed professionally.

• n = 18

  r = 5

  p = 1/4

  q = 3/4

• n = 18

  r = 5

  p = 1/4

  q = 1/4

• n = 18

  r = 5

  p = 25/75

  q = 75/75

• None of the above

FIND THE VARIABLES USED IN THE FOLLOWING PROBLEM

Barry Bonds has a career batting average of .298. What is the probability that he will get on base 6 times in 10 at bats?

• n = 10

  r = 6

  p = .298

  q = .702

• n = 10

  r = 4

  p = .298

  q = .702

• n = 16

  r = 6

  p = 6/10

  q = 4/10

• n = 10

  r = 6

  p = 4/10

  q = 6/10
