The probability that the 3 cards drawn from a pack of 52 cards are all red is
A box contains 4 white pens and 2 black pens. Another box contains 3 white pens and 5 black pens. If one pen is selected from each box, then the probability that both the pens are white, is
A drawer contains 50 bolts and 150 nuts, half of the bolts and half of the nuts are rusted if one item is chosen at random, then the probability that it is rusted or a bolt
One card is drawn from a pack of 52 cards each of the 52 cards being equally likely to be drawn, then the probability that the card drawn is an ace is

Five horses are in a race. Mr.A selects two of the horses at random and bets on them. The probability that Mr. A selected the winning horse is
If P (A∩B) = 1/3, P(A∪B) = 5/6 and P(A) = 1/2, then which of the following is correct?
A and B are independent events
A and B are mutually exclusive events
P(A) = P(B)
P(A) < P(B)
The probability that at least one of the events A and B occurs is 0.6. If A and B occur simultaneously with probability 0.2, then the value of
1.2
