Question

a number cube is rolled 450 times the number 3 comes up 67 times what is the theoretical probability of rolling a 3 write your answer as a fraction in simplest form. what is the experimental probability of rolling a 3 write your answer as a fraction in simplest form

Answer 1

theoretical probability = 1/6 ( because the 3 is one of 6 numbers on the cube)

experimental probability = number of times a 3 is obtained / number of times the cube is thrown

Answer 2

3 is the answer?

Answer 3

No
how many 3's were obtained in the experiment?

Answer 4

Look at the first line of your question.

Answer 5

67 times

Answer 6

right and what was the total number of throws made?

Answer 7

450

Answer 8

67/450 ?

Answer 9

right so plug those values into the formula for experimantal probability and you have ur answer

Answer 10

yes 67/450

Answer 11
