Lotto 6/42 - Probability Of A Set of 5 Numbers Being Drawn More Than Once

The probability of a set of 5 numbers being drawn more than once is 0.66%. That's a very, very low percentage -- less than 1%. Therefore, if 5 of your lotto numbers have been drawn before, most likely, they will not be drawn again. What you can do is to replace one of the 5 numbers with another number.

To check, however, if your numbers have won before, you need to go through each of the jackpot numbers of previous drawings and check if 5 of your numbers have been in the jackpot numbers. That won't be easy. You need a program, a spreadsheet program, at least, that can go through all the results automatically.
