Given:
Rolling a fair dice.
To find:
The theoretical probability of rolling a number less than 5.
Solution:
The possible numbers of rolling a dice are 1, 2, 3, 4, 5, 6.
Total outcomes = 6
Numbers less than 5 are 1, 2, 3, 4.
Favorable outcomes = 4
Now, the theoretical probability of rolling a number less than 5 is:
In decimal form, it can be written as:
In percentage form, it can be written as:
Therefore, the theoretical probability of rolling a number less than 5 in the fraction, decimal and percent are and
respectively.
