Where will you get your next pet? According to an Associated Press/Petside.com poll, half of all pet owners would get their next dog or cat from a shelter (USA Today, May 12, 2010). Consider a random sample of 10 pet owners and define x as the number of pet owners who would acquire their next dog or cat from a shelter. Assume that x is a binomial random variable.
a. For this binomial experiment, define a success.
b. For this binomial experiment, what is n?
c. For this binomial experiment, what is p?
d. Find P( x = 7).
e. Find P( x ≥ 3).
f. Find P( x > 8 ).
