1

(a)

3/5

Probability of an event lies between zero and one.

1

(a) True

(b) False

The probability expressed as percentage of a particular occurrence can never be less than zero

1

(a) False

(b) True

The sum of probabilities of all the outcomes of an experiment is greater than one.

1

(a) True

(b) False

For an event \(E,\ P(\overset { - }{ E } )=1-P(E)\) .

1

(a) True

(b) False

If a Random experiment is performed, then each of its outcome is known as favourable event.

1

(a) True

(b) False

The probability of an event that cannot happen is _______ Such an event is called________

1

(a)

0, impossible event. (e.g. Suppose a die is thrown and we have to determine the probability of getting 8. This type of event is called an impossible event and probability ofthis event is 0.)

The probability of an event that is certain to happen is ___________Such an event is called_____________

1

(a)

1, sure event. (e.g. The event of getting a number less than 7 in a single throw of a die is a sure event and its probability is 1.)

The sum of the probabilities of all the elementary events of an experiment is _______________

1

(a)

1,(e.g. Suppose a die is thrown, then P(getting1) + P(getting2) + P(getting 3) + P(getting 4)+ P(gerting 5) + P(getting 6) =1)

The probability of an event is greater than or equal to __________ and less than or equal to____________

1

(a)

0, 1, since, the probability of each event lies between 0 and 1.

Which of the following cannot be the probability of an event?

1

(a)

\(\frac{2}{3}\)

(b)

-1.5

(c)

15%

(d)

0.7
