I'm gonna play a hi lo game at freebitco.in
 the odds of 2X win are provided there at 47.5%

To win, BET HI and get a number higher than 5250 or BET LO and get a number lower than 4750


I dont understand how they arrived at 47.5%

I think it's a 50:50 chance of win:loss

Its gonna be either hi or lo ,right ?

Please help to make up my mind
