Each result 1, 2, 3, and 4 has an equal chance of occuring and that is 1/4.

So the player wins with probility 1/4 and loses with probability 3/4.

His expected return is:

r = (4)(1/4) + (0)(3/4) - 2 = -1

That is he gets $4 a quarter of the time$0 3/4 of the time and always pays
$2 to play. We could treat the cost to play differently to get: r = (2)(1/4) + (-2)(3/4) = -1. RonL 3. Is this for the player or house? What do you make of this? Chance of 3: 1/4 Payoff for 3:$2

Chance of non-3: 3/4
Payoff for non-3: -$2 Expected return: 1/4 *$2 + 3/4 * -$2 Is it correct? 4. Originally Posted by Infiniti Is this for the player or house? What do you make of this? Chance of 3: 1/4 Payoff for 3:$2

Is it correct?
That is the second of the calculations of return I gave (they are both for the
player)
