Question

calculate the probability of exactly 1 success in 4 tries.

p=0.27

1-p= 0.73

n=4

k=1

Expert Solution

Step 1

Ans- Here the random variable X has binomial distribution

With parameter n = 4, p = 0.27 & q = 1-p = 0.73 , k=1

We know,

P(X = k) = nCk*P^k*q^(n-k)

= n!/[k!(n-k)!]*P^k*q^(n-k)

Step by step
