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)
