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

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.
