Question

Assume that a procedure yields a binomial distribution with n= 2 trials and probablity of success of p= 0.80. Use a binomial probability table to find the probability that the number of successes x is exactly 1.

P (1)= ______

Answer 1

We have

n=2 and p=0.80

We want to find the probability that the number of successes X is exactly 1.

$\therefore P(X=1)=0.3200$   from statistical table

The required probability is 0.3200 .
