Answer:

4.35

Step-by-step explanation:

The expected value can be defined as: $\sum{x_i*p_i}$ where x_i = the payout, and p_i = the probability of it occurring.

This gives us the expression: $(1 * 0.35) + (2 * 0.2) + (5 * 0.1) + (8 * 0.2) + (10 * 0.15) = 0.35 + 0.4 + 0.5 + 1.6 + 1.5 = 4.35$

So the expected payout is 4.35

$x^3+3x^2+2x$

Step-by-step explanation:

<u>Definitions</u>

Integer: A whole number that can be positive, negative, or zero.

Consecutive Integers: Integers that follow each other continuously in the order from smallest to largest.

Product: The result of multiplying two of more values together.

Let x be the first integer.

Therefore, to find the consecutive integers, add 1 to each term:

x
x + 1
(x + 1) + 1 = x + 2

Therefore, the product of the first three consecutive integers is:

$\begin{aligned}x(x+1)(x+2) & = (x \cdot x+x \cdot 1)(x+2)\\& = (x^2+x)(x+2)\\ & = x^2 \cdot x+x^2 \cdot 2+x \cdot x+x \cdot 2\\& = x^3+2x^2+x^2+2x\\& = x^3+3x^2+2x\end{aligned}$
