The model that you could use to find the probability is a binomial model with parameters n = 3, X = 3 and p = 0.45.

For each TV bought, there are only two possible outcomes, either it is wide screen, or it is not. The probability of a TV bought being wide screen is independent of any other TV, hence the binomial distribution is used to solve this question.

What is the binomial probability distribution?

It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.

In this problem:

45% of its customers buy a wide-screen television, hence p = 0.45.

The experimental probability that the next three television-buying customers will buy a wide-screen television is P(X = 3) when n = 3.
