Determine the following probabilities. a. For $n=2$ and $\pi=0.13$, what is $P(X=0) ?$ b. For $n=9$ and $\pi=0.50$, what is $P(X=8) ?$ c. For $n=9$ and $\pi=0.60$, what is $P(X=7) $ ? d. For $n=3$ and $\pi=0.87$, what is $P(X=2) $ ? a. When $n=2$ and $\pi=0.13, P(X=0)=$ (Round to four decimal places as needed.) b. When $n=9$ and $\pi=0.50, P(X=8 =$ (Round to four decimal places as needed.) c. When $n=9$ and $\pi=0.60, P(X=7)=$ (Round to four decimal places as needed.) d. When $n=3$ and $\pi=0.87, P(X=2)=$ (Round to four decimal places as needed.) CS.VS. 1276|
