Question

At the Avonlea Country Club, 68% of the members play bridge and swim, and 85% play bridge. If a member is selected at random, what is probability that the member swims and plays bridge?

Answer 1

`Pr=68%=17/25`

Explanation:

If the percent of people who play bridge and swim is 68%, then the probability of a random member who plays bridge and swims is also 68%, thus the question answers itself.

To convert this percentage into a fraction, first you must realise that a percentage (%) is always out of 100. Therefore `68%` is equal to
`(68%)/(100%)`.
To put this as a fraction, first we remove the percentage symbols
`=68/100`, then we simplify,
`=34/50=17/25.` Thus the probability also comes to be `17/25` that a randomly picked member plays bridge and swims.
