Solution:
Correct option is
P(A) = 1 - P(Ac)
Explanation:
Event Ac is the complement of event A.
Total probability is always 1
0 Probability 1
So ,
P(A) = 1 - P(Ac)

Problem 3. Show the formula P((An B)U(A n B))- P(A) +P(B)-2P(AnB), which givgs the probability that exactly one of the events A and B will occur. [Compare with the formula P(AU B) P(A) P(B) - P(AnB), which gives the probability that at least one of the events A and B will occur.]
