Question

A fundraiser solicits donations by phone. The probability that a call does not result in a dontation is 72%. What is the probability that the fundraiser makes five calls and none result in a donation?

about 0.18%
about 14.4%
about 19.3%
about 36.0%

Answer 1

First convert into decimals. 72% = .72
The probability that it happens 5 times would be (.72) * (.72) * (.72) * (.72) * (.72) =
about .193 = 19.3%

Hope this helps!
