Question

A class rolled number cubes. Their results are shown in the table. What is the experimental probability of rolling each number?

Number----Occurences
1-------------------------51
2-------------------------47
3-------------------------49
4-------------------------51
5-------------------------50
6--------------------45

The experimental probability of rolling a 1 is ____?

Answer 1

51/293 or 51 out of 293 probability of rolling a 1.

Answer 2

The experimental probability of rolling a 1 is:
`(51)/(293)`

The experimental probability of rolling a 2 is:
`(47)/(293)`

The experimental probability of rolling a 3 is:
`(49)/(293)`

The experimental probability of rolling a 4 is :
`(51)/(293)`

The experimental probability of rolling a 5 is :
`(50)/(293)`

The experimental probability of rolling a 6 is:
`(45)/(293)`

Explanation:

We are given the occurrence of numbers on rolling a number cube as:

Number----Occurences

1---------------51

2--------------47

3--------------49

4--------------51

5--------------50

6--------------45

This means that the experimental probability of rolling a 1 is:

Ratio of number of times 1 come up and the total number of occurrence.

The total number of occurrence are: 51+47+49+51+50+45=293

This means that the experimental probability of rolling a 1 is:

`=(51)/(293)`

Similarly we can solve for others.
