Answer 2

Given:

90 students went on an activity day.

One of these students is chosen at random.

To Find:

The probability that this student participated in swimming.

Solution:

According to the formula of probability,

Probability = Number of favorable outcomes / Number of total outcomes.

Number of favorable outcomes = 1

Number of total outcomes = 90

So,

Probability = 1/90

Hence, the probability that one random student participated in swimming is 1/90.
