Question

While selecting a gift, girls want to ensure that they do not buy the same gift. Examine whether the events of selecting gifts by two girls are dependent or independent?

Answer 1

The two events are dependent events.

Explanation:

Assume there are `n` options are available for selection of one gift. As the girls want to ensure that they do not buy the same gift, if girl opting to select first selects a particular gift out of `n` options, second girl has to select from remaining `(n-1)` options.

Hence, the two events are dependent.
