To calculate expected value,
We can add up the probability of all possible events.
The 2 possible events are either winning $50 or losing the prize, which is $ - 50
Expected value =
50 x 40 % + (-50) x 60%
= $-10
So the answer is $-10

Answer:
Step-by-step explanation:
Let f(x) = 3x² - x³ - 3x + 5 and g(x) = x - 1 - x²
-x² + x - 1) -x³ + 3x² - 3x + 5(x - 2
-x³ + x² - x
-------------------------
2x² - 2x + 5
2x² - 2x + 2
----------------------
3
You can divide the whole expression by -3:
Recalling that
Let's compare the middle term:
So, we want to complete
Which differs from 
by 16. So, if we add 16 to both sides, we have
