An event A will occur with probability 0.5. An event B will occur with probability 0.6. The probability that both A and B will occur is 0.1.The conditional probability of A, given B(a) is 0.5(b) is 0.3(c) is 0.2(d) is 1/6(e) cannot be determined from the information given.We may conclude that(a) events a and B are independent.(b) events A and B are disjoint.(c) either A or B always occurs.(d) events A and B are complementary.(e) none of the above is...
