PROBABILITY, 1) The value of sun of probability of all the elementary events of an experiment, is (1,0,100, -1), 2) The probability of getting a multiple of 2 in a single throw of a die, , is (1/3, 2/3,%,%), 3) Rajesh speaks truth 3 out of 7 . The probability that he lies in narrating, an incident is (4/7 , 3/7 , 3/10, 7/10), , , , 4) Acoin is tossed 3 times . The probability of getting not more than 2 heads is, (1/8, 7/8, 1/16 , 3/8), 5) A bag contains 24 balls of which x are red , 2x are white and 3x are blue., A ball is selected at random .The probability that itis white is, (1/3, 5/6, 3/7, 7/24), 6) A box contains 20 balls bearing numbers 1, 2,3,4,5,......20.A ball is drawn at, random from the box . The probability that the number on the ball is a, a prime number is (13/20, 2/5 , 9/10 , 7/10 ), 7) One card is drawn at random from a well shuffled deck of 52 cards. The, probability of getting the jack of hearts is (%, 21/26 , 3/26, 1/52), 8) An event is very unlikely to happen . Which of the following number is closest, to its probability _ (0.0001, 0.1, 1.0, 0.001 ), 9) Which of the following cant be a probability of an event, (3/7 , 0.71, 41%,17/16), 10.
