The probability that event B occurs is 0.4, and the probability that events A and B both occur is 0.25. If the probability that either event A or event B occurs is 0.6, what is the probability that event A will occur?  Choose the most appropriate option:  A) 0.05  B) 0.45  C) 0.15  D) 0.5  E) 0.55
P(A or 0.45) = P (A) + P(0.45) - p(a n b)   0.6= 0.4 + P(A) - 0.25   P(A) = 0.45   Ans : 0.45
