No duplicate Combinations are calculated with n! / (r! * (n-r)! Where n will be 49 and r hw many you select,which is 6 for the normal lotto. This gives you a1 out of 13 983 816.
For powerball, n = 49 and r = 5, but the result is multiplied with 20 for the powerball, giving an answer of 1 out of 38 137 680

The extremely minute chances of winning is why I only play 2 lines with plus (R15) for Powerball and 2 lines both pluses (R20) for Lotto twice weekly.
Do you guys check your numbers or just hand your ticket in and let the machine check it? I just hand in and let the machine check when buying my next ticket - never even read the ticket. Goes machine, into wallet, back into machine after draw.
