The guidance department has reported that of the senior class, 2.3% are members of key club, k, 8.6% are enrolled in ap physics, p, and 1.9% are enrolled in both. determine the probability of p given k, to the nearest tenth of a percent.

The question is related to conditional probability .

It is given in the question that, the guidance department has reported that of the senior class, 2.3% are members of key club, K, 8.6% are enrolled in AP physics, P, and 1.9% are enrolled in both.

So we have ,

We have to use the following formula

Substituting the values, we will get

it goes right
