To find the experimental probability of rolling a 1 or a 5, we first need to find the total number of outcomes where a 1 or a 5 is rolled.
Total times rolling a 1 or a 5 = 10 (rolling a 1) + 6 (rolling a 5) = 16
Total number of outcomes = 10 + 6 + 4 + 8 + 6 + 6 = 40
Experimental probability of rolling a 1 or a 5 = $\frac{16}{40}$ = $\frac{4}{10}$ = $\frac{2}{5}$
The table shows the results of rolling a number cube with sides labeled 1 through 6 several times.
What is the experimental probability of rolling a 1 or a 5?
