Answer: - 0.027

Step-by-step explanation:

Win = any even number between (0 - 36)

Therefore,

Lose = any odd number between 0 —36 including 0

Assume Bet amount = $1

Expected value is calculate by summing all possible outcomes by their respective probabilities.

Expected value = [(p(winning) × net win value) + (p(losing +net loss value]

P(winning) = p(even) = 18/37

P(losing) = p(odd) +p(0) = 19/37

Net win value = $2

Net loss value = $-1

Expected value = [(18/37) × ($1) + (19/37) × (-$1)]

Expected value = 0.48648648 - 0.51351351

Expected value = - 0.027

In maths, Distance is described as the quantity of space between two points, and further calculation can be defined as follows:

Given Expression:

5x + 2 = 30\\\\2(x + 5) = 30\\\\5(x + 2) = 30\\\\2x + 5 = 30

To find:

distance=?

Solution:

5\ days\ \begin{cases} & \text{ if } \text{before school 2 miles}    \\  & \text{ if } \text{after school x miles} \end{cases}

\therefore 5(x+2)=30\\\\

\bold{5(x+2)=30}\\\\\bold{5x+10=30}\\\\\bold{5x=30-10}\\\\\bold{5x=20}\\\\

\bold{x=\frac{20}{4} }\\\\\bold{x=4}

Therefore, the final answer is "4 miles".
