Question

Fill in the blanks:

(i) Probability of a sure event is ...............

(ii) Probability of an impossible event is ................

(iii) The probability of an event (other than sure and impossible event) lies between .................

(iv) Every elementary event associated to a random experiment has .............. probability.

(v) Probability of an event A + Probability of event 'not A' = ................

(vi) Sum of the probabilities of each outcome in an experiment is ................

Answer 1

Fill in the blanks:

1. Probability of sure event is 1 as it is certain that it will occur always.

2. Probability of impossible event is 0 as it will never occur.

3. Probability of an event other than sure and impossible event lies between 0 and 1.

4. Every elementary event associated to a random experiment had equal probability

5. Probability of an event A + Probability of event ‘not A’ = 1.

6. Sum of the probabilities of each outcome in an experiment is 1
