- a. Which among the following numbers could be the
probability of anevent ?
0, −0.01, 0.75, 0.41, 1.34
- b. Which among the following numbers could be the probability of an event?
a.
To identify: The numbers that represents probability of an event.
Answer to Problem 1RE
The numbers that represent probability of an event are 0, 0.75, and 0.41.
Explanation of Solution
Given info:
The numbers are 0, -0.01, 0.75, 0.41, and 1.34.
Justification:
Rules of Probability:
- The probability of an event must lie between 0 and 1, inclusive.
- The sum of probabilities of all the outcomes is 1.
Here, it is observed that the numbers 0, 0.75, and 0.41 are lie between 0 and 1, inclusive. Hence, they represent the probabilities.
The values –0.01 and 1.34 does not lies between 0 and 1. That is,
Thus, the numbers represents probabilities are
b.
