Question 1192505: In 11!/r!(11,r)! - 6 = C(18,17), what is the value of r. Show the solution.
Answer by greenestamps(13200) (Show Source): You can put this solution on YOUR website!
The expression "(11,r)!" has no meaning. I will assume you mean "(11-r)!".
Your equation is
The values of C(11,r) are 1, 11, 55, ....
There is no r for which C(11,r) = 24.
The problem as you show it is faulty.
