The number of possible combinations is given by

... C(18, 3) = 18!/(3!(18-3)!) = 18·17·16/(3·2·1) = 816 . . . . possible combinations

_____

There are 18 ways to choose the first one; 17 ways to choose the second one, and 16 ways to choose the 3rd one. The same 3 students can be chosen in any of 3! = 6 different orders, so the product 18·17·16 must be divided by 6 to get the number of possible combinations in which order doesn't matter.

At the end of the night, Pizza Inn has of a pizza left. The 4 employees each took home the same amount of
Zina [86]

Answer:

Each employee took home 1/4 of pizza each.

Step-by-step explanation:

1. Picture a pizza as being a full 100%.

2. Since each employee took home the same amount of pizza, you need to divide the pizza equally by 4.    100 ÷ 4 = 25 this also equals 25/100

3. To reduce the fraction 25/100, you have to find a number that both the numerator and denominator can be divided by.

4. In this scenario, 25/100 can both be divided by 25.

5. 25 ÷ 25 = 1      100 ÷ 25 = 4

6. Therefore the final answer is each employee took home 1/4 of the pizza.
