Please help me with this anyone I beg

A)336

B) In how many ways can you arrange 8 people in 3 different chairs?

C) 21

D) You want to buy 3 cartoon books from a book store that has 7 cartoon books. In how many ways can you select?

Step-by-step explanation:

A) P(n, r) = P(8, 3)

Formula for permutation is;

P(n, r) = n!/(n - r)!

P(8, 3) = 8!/(8 - 3)!

P(8, 3) = (8 × 7 × 6 × 5!)/5!

5! will cancel out to give;

P(8, 3) = (8 × 7 × 6)

P(8, 3) = 336

B) In how many ways can you arrange 8 people in 3 different chairs?

C) C(n, r) = C(7, 2)

Formula for combination is;

C(7, 2) = n!/(n - r)!r!

Thus;

C(7, 2) = 7!/(7 - 2)!2!

C(7, 2) = (7 × 6 × 5!)/(5! × 2 × 1)

5! will cancel out to give;

C(7, 2) = 7 × 6/2

C(7, 2) = 21

D) You want to buy 3 cartoon books from a book store that has 7 cartoon books. In how many ways can you select?

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
