Question

Five people by individual insurance policies. According to the research, the probability of each of these people filing a claim for at least 5 years is 2/3. The probability that all five have not filed a claim after 5 years is what, and the probability that exactly three will have filed a claim after 5 years is what.

Answer 1

0.3292

Explanation:

`P(X=x)=C(n,x)p^xq^(n-x)\\\\P(X=3)=C(5,3)((2)/(3))^3((1)/(3))^2\approx0.3292`
