Question

Assume that a procedure yields a binomial distribution with nequals=55 trials and a probability of success of pequals=0.50 Use a binomial probability table to find the probability that the number of successes x is exactly 22.

Answer 1

Answer:-

Given That:-

Assume that a procedure yields a binomial distribution with nequals=55 trials and  a probability of success of pequals=0.50

Use a binomial probability table to find the probability that the number of successes x is exactly 22.

P=0.50; n = 55

we have asked to find :P(X=22)

This problem is of Binomial distribution .

we know that-

Hence

  

Therefore (Round to 4 decimal places)
