In a class of 30 students, 18 are men, 6 are earning a B, and no men are earning a B. If a student is randomly selected from the class, find the probability that the student is a man or earning a B. A) .8 B) .24 C) .54 D) .4

0.8

Step-by-step explanation:

The question here says that In a class of 30 students, 18 are men, 6 are earning a B, and no men are earning a B. If a student is randomly selected from the class, find the probability that the student is a man or earning a B.

Since the question says that 18 out of 30 students are men,6 out of the remaining people earn a "B" and non of the 18 men earn a "B".

The probability of picking a man or a person that earns a "B" is

18/30 (since there are 18 men out of the 30 students)

And 6/30(since there are 6 people that earn a "b")

The probability of picking a man or a "b" earner is

18/30 + 6/30

= 24/30 or 0.8
