Question

P(AIT) = __?
Answer Choices:
0.25.
0.36.
0.6.
0.75

Answer 1

Answer: Choice A) 0.25

=====================================================

Step-by-step explanation:

The notation P(A | T) is the same as saying P(A given T).

The "given T" means we know event T has happened. Therefore, the person we have selected has at least one tattoo. We focus only on the first column because of this.

We have m = 60 people ages 30-50 out of n = 240 people with tattoos.

This leads to the probability m/n = 60/240 = 1/4 = 0.25

There's a 25% chance we pick someone from the 30-50 age group if we know the person has at least one tattoo.

Answer 2

0.36 is chosen in the random
