Question

What is the probability that a subject selected at random from the above survey is a man or agrees with the survey statement?

a) 2/3
b) 21/50
c) 18/25
d) 7/40

Answer 1

Answer:

c) 18/25

Step-by-step explanation:

The total of all votes is 1000.

The total of all 'agree' votes is 420.

Since it is either agrees or is a man, we can add the 300 disagree male votes to 420, making 720 / 1000.

From there we simplify 720 / 1000 -> 18 / 25
