Answer 1

There are 48 people total in the spinning class and 15 of those people take both the spinning and yoga classes, so that would give you the probability of 15/48, which can be simplified to 5/16.

So there is a 5/16 chance that a person takes yoga class, knowing that they take spinning class.
