Question

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

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

Ok so I did this if I am right?

67/3 = 22.3
450/3 = 150

22.3/150 = ?
or
22/150 =

This where I get lost. I need a fraction. @whpalmer4 or @Taz_kapadia or @tcarroll010

Answer 1

Probability of an event =(Number of favorable outcomes)/(Total number of outcomes) Here, the number of favorable outcomes is the number of times 3 comes up. The number of times 3 comes up = 67 Total number of outcomes is the number of times the cube is rolled. Total number of times the cube is rolled = 450 Therefore, Probability of getting a 3 =67/450 Since 67 is a prime number, 67/450 is the final answer in simplest form.
