There are 7,315 different combinations, thus, the correct option is c
<h3>
How many combinations are there?</h3>
If we have a set of N elements, the number of different combinations of K elements (such that K ≤ N) of these N elements that we can make is:

In this case we have K = 4 and N = 22, replacing that, we get:

So there are 7,315 different combinations, thus, the correct option is c.

Answer:
C. 9/8
Step-by-step explanation:

Use KCF which means Keep the first fraction, Change the second fraction by flipping it and change the division sign to a multiplication symbol:

multiply the numerator together:
6 × 12 = 72
multiply the denominator together:
8 × 8 = 64
now the fraction is:

simplify further by dividing both numbers by 8:
72 ÷ 8 = 9
64 ÷ 8 = 8
so the fraction is 9/8
