If A and B are independent events then
Correct Answer: E
Question 9 Explanation:
If A and B are independent events then
P(A∩B) = P(A)P(B)
So finally we can say that,
P(AUB) = P(A) + P(B) – P(A∩B)
= P(A) + P(B) – P(A)P(B)
P(A∩B) = P(A)P(B)
So finally we can say that,
P(AUB) = P(A) + P(B) – P(A∩B)
= P(A) + P(B) – P(A)P(B)
P(A∪B) = P(A) + P(B) + (A∩B)
P(A∪B) = 0
P(A∪B) = P(A) + P(B) – (A∩B)
P(A∪B) = P(A) + P(B)
None of the above
