Question

A and B are two events.

P(A) = 0.6, P(B) = 0.3, P(A and B) = 0.1.
What is the value of P(A or B)?

Answer 1

Answer: 0.8

Explanation:

Answer 2

0.8

Explanation:

We can solve P(A or B) by using the following:

`P(AorB)=P(A)+P(B)-P(AandB)`

Since we know P(A) = 0.6, P(B) = 0.3 and P(A and B) = 0.1 we obtain:

`P(AorB)=0.6+0.3-0.1=0.8`
