Answer:
46.5
Step-by-step explanation:
We must find UNIQUE combinations because choosing a,b,c,d... is the same as d,c,b,a...etc. For this type of problem you use the "n choose k" formula...
n!/(k!(n-k)!), n=total number of choices available, k=number of choices made..
In this case:
20!/(10!(20-10)!)
20!/(10!*10!)
184756
One person gets 3 10ths of it and the other gets 7 10ths
21/2 is what you should get if you divide those two
2/6 is a fraction. the denominator has to be an even number.
