Anumber cube is rolled 30 times, and a number less than four comes up 22 times. what is the experimental probability that a number less than four is rolled? a. 1/6 b. 4/15 c. 11/15 d. 1/22

11/15 (choice C)

Divide 22 over 30 to get 22/30 = (11*2)/(15*2) = 11/15.

This is because we have 22 occurrences of what we want (rolling a number less than 4) out of 30 rolls total. Going from 22/30 to 11/15 is reducing the fraction as much as possible.

the answer is b

tube or goog would be a great resource to with that question
