Answer 1

Last Option

`P (B) = 0.6`

Explanation:

We have the Venn diagram that shows the probabilities of occurrence of 3 events A, B and C

In this case, since events A and B and B and C are non-disjoint events, then the probability of occurrence B is the sum of the probability that only B will occur plus the probability of occuring A and B plus the probability that B and C occur

This is:

`P (B) = 0.1 +0.3 +0.2`

`P (B) = 0.6`.
