Worked out from Powerball - official prize chart and odds (1 in 292,201,338 jackpot; 5 of 69 plus 1 of 26) and 3 other sources.
Odds here are exact; the money is not. Advertised jackpots are annuity values before tax, and a jackpot shared between winners pays a fraction of the headline figure. A positive expected value does not make a lottery ticket a good investment.

How this is worked out

4 steps
  1. C(69,5) = 11,238,513 main combinations, times C(26,1) = 26 bonus combinations = 292,201,338 tickets.
  2. Tickets matching exactly 5 main and 1 bonus: C(5,5) x C(64,0) x C(1,1) x C(25,0) = 1.
  3. Odds = 292,201,338 / 1 = 1 in 292,201,338.
  4. Expected value = probability x prize = 3.4223e-9 x 100000000 = 0.3422 per ticket, against a 2 ticket.
