stellarik [79]

Using the binomial distribution, it is found that there is a 0.1008 = 10.08% probability that exactly 18 of them say job applicants should follow up within two weeks.

<h3>What is the binomial distribution formula?</h3>

The formula is:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

C_{n,x} = \frac{n!}{x!(n-x)!}

The parameters are:

  • x is the number of successes.
  • n is the number of trials.
  • p is the probability of a success on a single trial.

The values of the parameters are given as follows:

n = 25, p = 0.62.

The probability that exactly 18 of them say job applicants should follow up within two weeks is P(X = 18), hence:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 18) = C_{25,18}.(0.62)^{18}.(0.38)^{7} = 0.1008

0.1008 = 10.08% probability that exactly 18 of them say job applicants should follow up within two weeks.
