Answer:
$132
If there are 10 friends and they each pay $12 + Amanda they will pay $132 in total
Solution
For this case the total outcomes are 6*6*6 = 216
The expected value is given by:
E(x) = p* X1 + (1-p)*X2
Where p = probability of success (sum of cubes 16 or greater)
and 1-p = probability of failure
X1 =
Answer:
-3 times -3 that is -4 exponent two in expanded form
5x^4 - 3x^3 + 6x - (3x^3 + 11x^2 - 8x) =
5x^4 - 3x^3 + 6x - 3x^3 - 11x^2 + 8x =
5x^4 -6x^3 - 11x^2 + 14x <== yep, I got the same thing
