Question

What is the probability that a randomly selected student will study more than three hours and earn a 71 to 90?

Answer 1

Answer: 0.375

Step-by-step explanation

The probability can be given by:

`P=\frac{\text{ desired event}}{\text{ total outcome}}`

In our case, we could say that the desired event is:

`P=(18)/(48)=(3)/(8)=0.375`
