Answer:
Correct option: D. 0.6
Step-by-step explanation:
The Venn diagram shows that there is no intersection between events A and B, so we have that:
P(A and B) = 0
Therefore the probability of A or B is:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = P(A) + P(B)
So, If the sum of the probabilities needs to be 1, we have that:
Total = P(A or B) + P(neither)
Total = P(A) + P(B) + P(neither)
1 = 0.2 + P(B) + 0.2
P(B) = 1 - 0.2 - 0.2 = 0.6
So the correct option is D.
