0.0013 = 0.13% probability that no more than four out of fifteen people used an online travel website when they booked their hotel
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they booked the hotel using an online travel website, or they did not. Each person is independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Suppose that the probability that a person books a hotel using an online travel website is 0.68.
This means that![p = 0.68](/tpl/images/1053/5386/dfdea.png)
Sample of fifteen:
This means that![n = 15](/tpl/images/1053/5386/7b244.png)
What is the probability that no more than four out of fifteen people used an online travel website when they booked their hotel
So
0.0013 = 0.13% probability that no more than four out of fifteen people used an online travel website when they booked their hotel
