Question

If the probability of passing an exam is 0.8, what is the probability that it writes?

A. 0.2
B. 0.5
C. 0.8
D. 0.9

Answer 1

The probability that the student passes the exam is 0.8.

Step-by-step explanation:

To calculate the probability of passing the exam, we can subtract the probability of failing from 1. Since the probability of passing is 0.8, the probability of failing is 1 - 0.8 = 0.2.

So, the probability that the student fails is 0.2. Therefore, the probability that the student passes is 1 - 0.2 = 0.8.
