Question

a six sided number cube numbered 1 through 6 is rolled 300 times. the number 3 comes up 66 times. What is the experiment probability of rolling a 3.

Answer 1

The probability is obtained by calculating the quotient in between the number of time you get a 3 over the total number of rollings.

Then, based on the information of the question, you have:

p = 66/300 = 0.22

the probability of getting a 3 is 0.22, which is the same that the probability is 22%.
