Odds of winning the jackpot - 1 in 116,531,800 - 0.0000000086
Odds of winning 5 + 1 - 1 in 6,473,989 - 0.00000015
odds of no one winning the jackpot with 120million players
(chance of not winning with 1 ticket)^number of tickets
(1 - 0.0000000086)^120,000,000 =
(0.9999999914)^120,000,000 = 0.35709
I think we are good at this point, that shows the odds of no one winning the jackpot with 120million tickets sold being 36% sounds fair enough.
So we need the chance of you winning either the jackpot or the second tier with no one else winning the jackpot.
chance of winning 5+2 or 5+1 = 0.0000000086+0.00000015 (am I allowed to add these together??) = 0.000000163
so chance of you winning 5+2 or 5+1 and no one winning the jackpot is 0.000000163 x 0.35709 = 0.000000058
ok that might be right this time.
You could probably also take into account the chance of winning the jackpot with 5+0 but there is so little chance of that happening because with 120,000,000 tickets the chance of no one getting 5+1 is 0.0000000089 which is near enough exactly the same as winning the main jackpot with 1 ticket.
