Which of the following can be the probability of an event
a. -0.04
b. 1.004
c. 18/23
d. 8/7

Solution:

Occurrence of any outcome for a random experiment is an event.

The possibility of the number of occurrences of a particular outcome of a randomly selected experiment is probability.

It is a dimensionless numeric value which can range from 0 to 1

It cannot be a negative number or more than 1.

If the outcome is 1, there is a 100% chance of an outcome to occur.

If the outcome is more than 1, the possibility of occurrence is more.

a. -0.04 cannot be the probability as it is negative.

b. 1.004 cannot be the probability as it is more than 1.

c. 18/23 = 0.782 is the probability of an event.

d. 8/7 = 1.142 cannot be the probability as it is more than 1.

Therefore, the probability of an event is 18/23.
