Question

What is a probability that a randomly selected student will prefer math given they are in 12th grade ??

Answer 1

To compute the probability, we need to get first the total number of selected students in 12th grade. We have

`10+17+28+13=68`

Out of this number of 12th-grade students, 28 students prefer math. To get the probability, divide this number by the total number of students in 12th grade. We have

`P=(28)/(68)=0.412`

Answer: 0.412
