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.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
