Question

find the probability of exactly three successes in eight trials of a binomial experiment in which the probability of success is 45%.
enter q, or the probability of failure, as a decimal.
q = ?

Explanation:

Step1: Recall the formula for probability of failure

In a binomial experiment, \(q = 1 - p\), where \(p\) is the probability of success.

Step2: Substitute the value of \(p\)

Given \(p=0.45\), then \(q = 1 - 0.45\).

Answer:

\(q = 0.55\)
