How Lottery Odds Are Calculated
Lottery odds use combination math: C(n,k) = n! / (k! × (n-k)!). For Powerball: C(69,5) × C(26,1) = 11,238,513 × 26 = 292,201,338. That's your 1 in 292.2 million odds.
Expected Value of a Lottery Ticket
A $2 Powerball ticket has an expected value of about $0.93 — meaning on average, you lose $1.07 per ticket. The house edge is roughly 47%. Only during massive jackpots (>$600M) does the expected value approach $2.
