**helper**, Wednesday, January 12, 2011 at 4:11pmCombination of 40 taken 6 at a time

nCr = nPr/r!

nPr = n!/(n - r)!

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

n = 40, r = 6

40C6 = 40P6/6! = 40!/34! / 6!

= 40!/(6!*34!)

= 40*39*38*37*36*35/(6*5*4*3*2*1)

= 2,763,633,600/720

= 3,838,380

I am not a tutor but this is right IF this is a combination of 40 taken 6 at a time (I checked my math in an online calculator)
