Question 1086772
<font color="black" face="times" size="3">Use the Combination Formula (n C r). In this case, the number of items selected is r = 7 and this is from a pool of n = 12 items total.


n C r = (n!)/(r!(n-r)!)


12 C 7 = (12!)/(7!*(12-7)!)


12 C 7 = (12!)/(7!*5!)


12 C 7 = (12*11*10*9*8*7!)/(7!*5!)


12 C 7 = (12*11*10*9*8)/(5!) ... note how the 7! factorial terms cancel


12 C 7 = (12*11*10*9*8)/(5*4*3*2*1)


12 C 7 = (95040)/(120)


12 C 7 = 792


Answer: 792
