A fair dice has six faces numbered 1, 1, 1, 2, 3, & 4.
The dice is rolled twice and the number is shown recorded each time.
Find the probability that the sum of the two numbers recorded is at least 4.
The answer is:21/36
Can you please explain how to get to answer?

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.
