How unlikely is that jackpot, really?
Lottery odds use combinations C(n,k) because the order you pick numbers doesn't matter — picking 6 from 49 gives C(49,6) = 13,983,816 possible combinations, meaning 1-in-nearly-14-million odds.
Lotteries like Powerball add a second pool (the bonus ball) — the total odds become C(69,5) × C(26,1) = about 1 in 292 million, because you need to match both the main numbers AND the separate bonus number.
