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

Answer:

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

Step-by-step 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.
