Answer:
60%
Step-by-step explanation:
The table with proper formatting is attached below.
We have to find the probability that a randomly selected person is 41-55 in age or prefers drinking Dr. Fizz.
Total number of people = 100
People in range 41 - 55 = 30
People who prefer Dr. Fizz = 30
People in range of 41 - 55 and prefer Dr. Fizz = 0
The general formula of probability in case of OR of two events is:
P ( A or B ) = P(A) + P(B) - P( A and B)
So for the given case we can write:
P (Person is in 41-55 range OR prefer Dr. Fizz) = P (Person is in 41 - 55 range) + P(Prefers Dr. Fizz) - P(Is in 41-55 range And prefers Dr. Fizz)
P (Person is in 41-55 range OR prefer Dr. Fizz) = 30/100 + 30/100 - 0/100
= 60/100
= 60%
Thus there is a 60% probability that a randomly selected person is 41-55 in age or prefers drinking Dr. Fizz
