Question

A person is picked at random. What is the probability that this person is not a child whose favourite drink is fruit juice?

a) P(Not a child)×P(Fruit juice)
b) 1−P(Child and Fruit juice)
c) P(Adult or Not Fruit juice)
d) P(Child)+P(Not Fruit juice)

Answer 1

The probability of a person not being a child whose favorite drink is fruit juice can be found using 1-P(Child and Fruit juice).

Step-by-step explanation:

The probability that a person is not a child whose favorite drink is fruit juice can be found using option b) 1−P(Child and Fruit juice).

To calculate this probability, we first need to find the probability of a person being a child and preferring fruit juice. Let's assume that P(Child) represents the probability of selecting a child and P(Fruit juice) represents the probability of selecting a person who prefers fruit juice.

So, P(Child and Fruit juice) = P(Child) × P(Fruit juice).

Finally, we can use the formula 1 - P(Child and Fruit juice) to find the probability that a person is not a child whose favorite drink is fruit juice.
