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

Answer:

The experimental probability of rolling a 1 is: $\dfrac{51}{293}$

The experimental probability of rolling a 2 is: $\dfrac{47}{293}$

The experimental probability of rolling a 3 is: $\dfrac{49}{293}$

The experimental probability of rolling a 4 is : $\dfrac{51}{293}$

The experimental probability of rolling a 5 is : $\dfrac{50}{293}$

The experimental probability of rolling a 6 is: $\dfrac{45}{293}$

Step-by-step 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:

$=\dfrac{51}{293}$

Similarly we can solve for others.
