At west high school, 16% of the student population is taking a calculus course, 11% is taking a physics course, and 4% is taking both. find the probability that a student chosen at random is taking a calculus course, given that the student is taking a physics course

The probability is:

Step-by-step explanation:

It is given that:

16% of the student population is taking a calculus course.

11% is taking a physics course.

and 4% is taking both.

Now we are asked to find the probability that the student is taking a calculus course given that he is taking physics course.

Let A denote the event of taking a calculus course.

B denote the event of taking a physics course.

A∩B denote the event of taking both.

Let P denote the probability of an event.

We are asked to find:

                  P(A|B)

We know that:

From the information we have:

              Hence,

step-by-step explanation:

1

just sum

10 + 10 = 20
