Consider the following binomial experiment: A company owns 4 copiers. The probability that on a given day any one copier will break down is 23/50. What is the probability that at least 2 copiers will break down on a given day?

Following are the calculation to the given binomial experiment:

Given:

Please find the given question.

To find:

probability =?

Solution:

Let the   probability of one copy is broken down then

Using the binomial distribution:

 Calculating the probability in which the copy of 2 will break down on a given day:

 Therefore, the final answer is "0.2304".

Step-by-step explanation:

Given that:

Number of copiers with the company = 4

It is a binomial experiment.

Probability that on a given day, one copier will break down =

= 0.46

= 0.54
