Carlson jewelers permits the return of their diamond wedding rings, provided the return occurs within two weeks of the purchase date. their records reveal that 10% of the diamond wedding rings are returned. five different customers buy a wedding ring. what is the probability that none of the customers return a ring?

The probability that non of the customers return a ring is 0,59

Explanation:

According to their records, 10% of the rings are returned. This means 1 of every 10 rings are returned.

This also means that 9 of 10 every rings are not returned.

5 different customers (C1, C2, C3, C4, C5) buy a wedding ring = those are independents events, which means that the return of the ring by one customer has no effect on the probability that another customer will also return it.

P(C1 ∩ C2 ∩ C3 ∩ C4 ∩ C5) = P(C1)P(C2)P(C3)P(C4)P(C5)

0,9 X 0,9 X 0,9 X 0,9X 0,9 = = 0,59
