The probability that this person does not make use of the facility is 7/130

How to solve for the probability

61+68+60 - 25-28-19 + 6

= 123

The total number of person in the sport center is given as 130

We have 130 - 123 = 7

This means that there are a total of 7 persons that do not make use of this facility.

Hence the probability of a person not using the facility is 7/130
