A ball is drawn from each bag, find the probability that both are black. 1) 5/24 2) 1/4 3) 1/8 4) 1/2  Hence, option 2. Q7) Two cards are drawn together from a pack of 52 cards at random. What is the probability that both the cards are diamonds? 1) 1/16 2) 3/52 3) 1/442 4) 1/17  Hence, option 4. Q8) Two cards are drawn together from a pack of 52 cards at random. What is the probability that one card is a diamond and one card is a spade? 1) 13/102 2) 13/17 3) 25/102 4) 1/16  Hence, option 1. Q9) A coin is tossed 5 times. What is the probability of getting the following sequence HTTHT? 1) 1/32 2) 1/2 3) 1/16 4) 1/64
Probability of getting HTTHT on tossing a coin 5 times is 1/32. Hence, option 1. Q10) A man is known to speak truth 5 out of 8 times. He throws a dice and reports that it is a four. Find the probability that it is actually a four? 1) 1/6 2) 3/4 3) 1/4 4) 5/48  Hence, option 3. |
