NEED HELP PLEAS ON BOTH QUESTIONS PLEAS

1. B (40- 3n)

2.c (86)

Step-by-step explanation:

1. The shirts cost 3n. So you do 40- 3n(what the shirts cost) to find the amount of change he will recive.

2. Just plug the numbers in- 1.8(30) + 32=86.

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.
