So for this question, like it says here, if we roll our six -sided fair die, if we roll a 1, we win 20, if we roll a 2, we win 29, 3, we win 26, 4, win 21, 5, you win 15, and 6, you win 30.

What's the expected value for this game? what we have to do is sum up the, so we write the sum of the probability multiplied by the winning.
00:31
Or the, yeah, i'll say the winnings.
00:34
So, multiplied by w.
00:37
So this will be equal to the expected value.
00:41
Mew is equal to.
00:43
So the probability to roll any...
00:50
The probability of any dice roll is one sixth.
00:54
So this will be the same for all dice rolls.
00:58
So they will all be one sixth because we have a fair die.

Sorry for the messy handwriting...
