SOLUTION:
From given data,
Perform the indicated calculation:
7C4 / 12C4
We use the formula
nCr = n! / r!(n-r) !
7C4 / 12C4 = ( 7! / 4!(7-4) ! ) / (12! / 4!(12-4) !)
7C4 / 12C4 = (7! / (4! * 3!)) / (12! / (4!*8!))
7C4 / 12C4 = [(7*6*5*4*3*2*1)/((4*3*2*1)*(3*2*1))] / [(12*11*10*9*8*7*6*5*4*3*2*1)/((4*3*2*1)*(8*7*6*5*4*3*2*1))]
By canceling the common terms in numerator and denominator then we get
7C4 / 12C4 = (7*5) / (3*11*5*3)
7C4 / 12C4 = 35/495
7C4 / 12C4 = 0.0707
