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.

I hope I helped!
