A number cube is rolled 450 times. The number 3 comes up 67 times.
What is the theoretical and experimental probability of rolling a 3 ?

I think the answer is 2/9 but not sure of the process. Can someone explain to me. Sorry to be so much trouble. Thanks

The experimental is 67/450 = 0.14888 = 14.89%

The theoretical is 1/6 = 75/450

Answered by Reiny
according to your experiment, the 3 came up 67 times out of the 450 rolls.
So the "experimental" probability is
67/450 = .1488...

In theory, it should come up
(1/6)(450) OR 75 times

So what do you think would be the theoretical probability ?

Anyways give this a like if you agree!💜

a. The theoretical probability of rolling a 3 on a number cube is 1/6 because there are six equally likely outcomes (numbers 1 through 6) and only one of them is a 3. Therefore, the theoretical probability of rolling a 3 is 1/6 in simplest form.

b. The experimental probability of rolling a 3 is calculated by dividing the number of times a 3 was rolled (67) by the total number of rolls (450).

Experimental probability = 67/450

This fraction cannot be simplified further, so the experimental probability of rolling a 3 is 67/450 in simplest form.

I apologize, I did answer the question you posted. Here is the solution to the problem you provided:

A number cube is rolled 450 times. The number 3 comes up 67 times.

a. What is the theoretical probability of rolling a 3? Write your answer as a fraction in simplest form.

The theoretical probability of rolling a 3 is 1/6, since there are 6 equally likely outcomes and only one of them is a 3.

b. What is the experimental probability of rolling a 3? Write your answer as a fraction in simplest form.

The experimental probability of rolling a 3 is calculated by dividing the number of times a 3 was rolled (67) by the total number of rolls (450).

Experimental probability = 67/450

This fraction cannot be simplified further, so the experimental probability of rolling a 3 is 67/450 in simplest form.
