Question

Nicole is rolling a dice for a probability project. What is the theoretical probability that she will roll a 1 or a 4? Write your answers as a simplified fraction OR a percent

Answer 1

Answer:

$\frac{1}{3}$

Step-by-step explanation:

Given: Nicole is rolling a dice for a probability project

To find: theoretical probability that she will roll a 1 or a 4

Solution:

Theoretical probability expresses the chances that something will occur. It is equal to the number of favorable outcomes divided by the total number of outcomes.

Total number of outcomes = 6

Theoretical probability that she will roll a 1 or a 4 = $\frac{1}{6} +\frac{1}{6} =\frac{2}{6}=\frac{1}{3}$
