A roulette wheel has the numbers 1 through 36, 0, and 00. A bet on three numbers pays 11 to 1 (that is, if you bet $1 and one of
OLga [1]

Answer:

You are expected to lose $0.05 (or win -$0.05)

Step-by-step explanation:

Since the roulette wheel has the numbers 1 through 36, 0, and 00, there are 38 possible outcomes.

In this bet, you are allowed to pick 3 out of the 38 numbers. Thus, your chances of winning (P(W)) and losing (P(L)) are:

P(W)=\frac{3}{38}\\P(L) = 1 - P(W)\\P(L) = \frac{35}{38}\\

The expected value of the bet is given by the sum of the product of each outcome pay by its probability. Winning the bet means winning $11 while losing the bet means losing $1. The expected value is:

EV = (11*\frac{3}{38}) -(1*\frac{35}{38})\\EV = -\$0.0525

Therefore, with a $1 bet, you are expected to lose roughly $0.05

- 16m’n-(-25m’n)+(-7m’n)Which of the following is equivalent to the expression above?
Westkost [7]

As a rule , - times - = + and - times + = -

\begin{gathered} -16m^2n-(-25m^2n)+(-7m^2n\text{ ) } \\ =-16m^2n+25m^2n-7m^2n\text{  ( based on the rule above )} \\ =+9m^2n-7m^2n\text{    ( -16 + 25 = + 9 )} \\ =+2m^2n \end{gathered}

Therefore the correct answer to the question is 2m squared n
