oki need someones help that knows their math asap?
A roulette wheel in Las Vegas has 18 red slots and 18 black slots numbered alternately with the numbers 1 through 36. Two green slots are numbered 0 and 00. The winning number is determined by the slot into which a single marble rolls. Players are not allowed to bet on green. The house wins all bets if 0 or 00 comes up. A $1 bet on a single roll of a roulette wheel wins $36 if the marble lands in the slot for the number selected. If that number doesn’t come the person placing the bet loses the $1. What is the expected value of such a bet?
There are 38 slots the ball can fall into (18 red + 18 black + 2 green).
If you bet $1 on one number, then if the ball falls into the slot you bet on, you get back $36. But it cost you $1 to play, so you actually win only $35. If it falls into any of the other 37 slots, you lose your dollar. So the expected value of this bet is
(1/38)$35 + (37/38)(-$1) = ($35 - $37)/38 = (-$2)/38 = - 5.263 cents
