Expected value, explained with ₦500 stakes
If you read one thing on this site, read this. It's the idea that separates people who bet for entertainment from people who bet with an edge — and it takes five minutes.
Read it now“Imagine a coin that pays ₦2,100 when it lands heads and costs you ₦500 to flip. Heads comes up half the time. Over a hundred flips you stake ₦100,000 and win about ₦105,000 — so you're up ₦2,000. Not because you can predict a coin. Because you were being overpaid for the risk.
That's the whole game. A bet at 1.20 on a team that wins 78% of the time is a bad bet, even though they'll usually win. A bet at 3.40 on a team that wins 35% of the time is a good bet, even though you'll lose it most weekends…”
