Question

According to the Venn diagram, if P(A)=0.3 and P(B)= 0.35, what is P(A B)?

PLEASE HELP MEEE!!​

Answer 1

A.
`P(A\cup B)=0.55`

Explanation:

From the Venn diagram,

`P(A) = 0.3, P(B) = 0.35, and P(A\cap B) = 0.10`

Therefore, from the rule of Addition of probabilities,

`P(A\cup B )=P(A)+P(B)-P(A\cap B)\\P(A\cup B )=0.3+0.35-0.10\\P(A\cup B )=0.55`

Therefore, option A is correct.
