Question 1: 155 people visit a Leisure Centre. 97 use the waterslide. 43 use the sauna. 43 people do not use
either the water slide or the sauna. If one person is chosen at random, find the probability that
this person uses both the waterslide and the sauna.

28/155

Step-by-step explanation:

To find people who do use the waterslide and/or the sauna subracter 43 from 155 to get 112.

To find the people who only use the sauna subtract 97 from 112 to get 15.

To find people who use both the waterslide and the sauna subtract 15 from 43 to get 28.

The probability of a person who uses both the waterslide and the sauna is 28/155.
