Whats the gamble formula

<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 $\tt{.50 = \frac{2}{3}* \times }$

Prove that (n+5)^2 - (n+3)^2 is a multiple of 4 for all positive integer values of n.

Drupady [299]

Answer:

(n+5)² - (n+3)² =

= (n² + 10n + 25) - (n² + 6n + 9)

= n² + 10n + 25 - n² - 6n - 9

= 4n + 16

= 4(n + 4) ⋮ 4

A sphere's radius is multiplied by 3. How is its surface area affected?

Montano1993 [528]

Answer:

Step-by-step explanation:

For all shapes, the surface area will go up by a factor of 9 (3^2). This is true of spheres, cones, cubes, pyramids, torusses, everything.

The surface area of any body is proportional to the square of any linear dimension. Triple a linear dimension and you get a 9 fold increase in surface area. This is as true for pretzels as it is for spheres and cubes.
