Only these are direct variations:

<span>Songs are 99 cents each to download.
Tickets for rides at the fair are $1 each.

Because, for each of them, the total value will be always the product of the number of items times a constant (the unit price).

Whats the gamble formula

Juli2301 [7.4K]

$\quad\quad\quad\quad\huge\tt{Answer \: ☕}$

<h3>The formula looks like this: </h3>

(Probability of Winning) x (Amount Won per Bet) – (Probability of Winning) x

(Amount Won per Bet) – (Probability of Losing) x (Amount Lost per Bet).

So, in our example we would plug in these variables, a 50% chance of winning, winning $6, a 50% chance of losing, and $5 lost.

<h3>The formula for expected value = </h3>

(fair win probability) x (profit if win) - (fair loss probability) x (stake).

This is the formula in the OddsJam sports betting expected value calculator.

$\LARGE \tt{Example: \color{purple}{ Amount \: of \: Win}}$

┈──────────────────────────┈

$\quad\quad\quad \large\tt{Solve \: for \: \color{red}{Amount \: of \: Win}}$

$\quad\quad \quad\quad \large\tt{x = Amount \: of \: Win}$

_ _ _ _ _ _ _ _ _ _ _ _

$\quad\quad\quad \implies\sf{0 = \frac{2}{3} * \times - .50}$

$\quad\quad\quad\implies\tt{0 + .50 = \frac{2}{3}* \times - .50 + .50 }$

$\quad\quad\quad\implies\tt{0 + .50 = \frac{2}{3} * \times + 0}$

$\quad\quad\quad\implies \color{blue}\boxed{ \tt \color{red}{.50 = \frac{2}{3}* \times }}$

_ _ _ _ _ _ _ _ _ _ _ _

Therefore, the amount of win is $\tt{.50 = \frac{2}{3}* \times }$

The price of a skateboard is reduced by 25%. The original price was $120. Find the new price.

8_murik_8 [283]

New price = <u>90 dollars</u>

<u></u>

25% of 120 = 30

Price is reduced 25% from 120 so,

120 - 30 = 90

Amount of discount = 30
