a) 110,880

b) 8.61x10^37

c) 7.18x10^19

Step-by-step explanation:

To find the amount of options, use the following combination equation.

n!/[r! * (n - r)]

In this equation, n represents the amount of possible options and r represents the amount being chosen at a time. We can now calculate out the answer for each possibility.

a) In this case, n would equal 12 and r would equal 6.

n!/[r! * (n - r)]

12!/[6! * (12 - 6)]

479001600/[720*6]

479001600/4320

110,880

b) In this case, n would equal 36 and r would equal 6

n!/[r! * (n - r)]

36!/[6! * (12 - 6)]

3.72x10^41/[720*6]

3.72x10^41/4320

8.61x10^37

c) For this one, n would equal 24 and r would equal 6. We would also then have to divide the answer at the end by 2.

n!/[r! * (n - r)]

12!/[6! * (12 - 6)]

6.20x10^23/[720*6]

6.20x10^23/4320

1.44x10^20 ÷ 2 = 7.18x10^19
