A case of 24 cans contains 1 can that is contaminated. Three cans are to be chosen randomly for testing.
(a) How many different combinations of 3 cans could be selected?
Number of different combinations.
24C3 = 2024
---------------------
(b) What is the probability that the contaminated can is selected for testing? (Round your answer to 3 decimal places.)
P(bad can included) = 1 - P(bad can not included)
= 1 - [23C3/24C3]
---
= 1 - [1771/2024]
---
= 0.125
