Chapter 6, Problem 101(choose chapter or problem)
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 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

QUESTION:
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 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
ANSWER:Step 1 of 2
Probability that eggs contains salmonella bacteria,
X = the number of contaminated eggs when Joe uses 3 chosen at random
We have determine the type of distribution:
