Joe reads that 1 out of 4 eggs contains salmonella bacteria. So he never uses more than 3 eggs in cooking. If eggs do or don’t contain salmonella independently of each other, the number of contaminated eggs when Joe uses 3 eggs chosen at random has the following distribution:

a. Binomial; n = 4 and p = 1/4

b. Binomial; n = 3 and p = 1/4

c. Binomial; n = 3 and p = 1/3

d. Geometric; p = 1/4

e. Geometric; p = 1/3

Select the best answer.
