Question

a class rolled number cubes. their results are shown in the table. what is the experimental probability of rolling number 1? round your answer to the nearest tenth.

Answer 1

Answer: 15.7%

Step-by-step explanation

The probability of an event A is given by:

`P(A)=\frac{\text{ occurence of events A}}{\text{total occurrences}}`

In our case, event A is rolling the number 1. Thus, we have 42 occurrences, while the total occurrences are:

`\text{ Total occurrences}=42+44+45+44+47+46=268`

Then:

`P(A)=(42)/(268)=0.1567`

Changing to percent:

`0.157*100\%\approx15.7\%`
