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?

Answer:

\(\frac{2}{5}\)

Step-by-step explanation:

Given :

Outcome  Number of times outcome occurred

1                          10

2                          6

3                          4

4                          8

5                          6

6                          6

To find: What is the experimental probability of rolling a 1 or a 5?

Solution:

No. of times dice rolled =  10+6+4+8+6+6=40

No. of times 1 occured = 10

So, probability of getting 1 = \(\frac{10}{40}\)

No. of times 5 occured = 6

So, probability of getting 5 = \(\frac{6}{40}\)

So, probability of rolling a 1 or a 5 =  \(\frac{10}{40}+\frac{6}{40}\)

                                                        =  \(\frac{16}{40}\)

                                                        =  \(\frac{2}{5}\)

Hence the experimental probability of rollin 1 or a 5 is \(\frac{2}{5}\).
