Question

Given a sequence of Bernoulli trials with n=7 and p=0.8 , find the binomial probabilities for the k values given below.
k=0
k=1
k=2
k=3

Answer 1

Probability of "k" successes =
\[\large \left(\begin{matrix}n \\ k\end{matrix}\right)p^k(1-p)^{n-k}
\]Plug in the values.

Answer 2

\[
\large \left(\begin{matrix}n \\ k\end{matrix}\right) =
\frac{n!}{(n-k)! * k!}

\]

Answer 3

okay let me see
