The probabilities are 0.65 that there will be strike, 0.80 that the construction job will be completed on time if there is no strike, and 0.32 that the construction job will be completed on time if there is a strike, the probability that the construction job will be completed on time is

Out of all possible three digit numbers, a number is picked at random. The probability that the number does not contain the digit 6 is _______.

Let A and B be two events such that P(AUB)’ = 1/6, P(A∩B) = ¼ and P(A’) =1/4, where A’ stands for complement of event A. Then events A and B are

If two dice are thrown and it is known that atleast one of them is 6. What is the probability that both of them is 6__________ (Round upto 2 decimal places).

Consider there are 5 fair coins and 4 unfair coins where we toss unfair coin then probability of getting heads is 1/3. We put these 9 coins in a bag. The probability of getting fair coin if tail is already shown

If A and B are two events such that P(A) ≠ 0 and P(B) ≠ 1, then P =
