Direction: In the following questions, a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements, mark the correct
answer as
Assertion : A fair die is rolled. Then the probability of getting an even number is 1/2 and probability of getting an odd number is 1/2.
Reason : Possible outcomes when a fair die is rolled is (1, 2, 3, 4, 5, 6).
Direction: In the following questions, a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements, mark the correct
answer as
Assertion : If E1, E2 , .........., En are n elementary events associated to a random experiment, then P(E1) + P(E2) PE +.....+ P(En) = 1
Reason : For any event ‘A’ associated to an experiment, we have -1 ≤ P(A) ≤ 1
Direction: In the following questions, a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements, mark the correct
answer as
Assertion : In a class there are x boys. and y girls, A student is selected at random, then the probability of selecting a girl is y/x.
Reason : Probability of an event E of an experiment is ratio of the number of trials in which event E has happened to the total number of trials.
Direction: In the following questions, a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements, mark the correct
answer as
Assertion : A die is thrown. Let E be the event that number appears on the upper face is less than 1, then P(E) = 1/6
Reason : Probability of impossible event is 0.
Direction: In the following questions, a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements, mark the correct
answer as
Assertion : Tossing a coin 50 times is called an event.
Reason : The possible outcomes of an experiment are called events.
Direction: In the following questions, a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements, mark the correct
answer as
Assertion : A coin is tossed two times. Probability of getting at least two heads is 1/4.
Reason : When a coin is tossed two times, then the sample space is {HH, HT, TH, TT}
A die is rolled if the number on a die is even then a coin is tossed once and if the number on a die is odd, then a coin is tossed twice. Match the events in Column-I with their probabilities in Column-II
A NGO selected 2000 families at random and surveyed them to determine number of children in a family. The data is given below:
If one family is chosen at random then, match the Column-I with their corresponding probabilities in Column-II.
