The answer is 39.

Step-by-step explanation:

The first term of arithmetic sequence is 1:

and the formula of arithmetic sequence is:

20th term of the arithmetic sequence will be:

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.
