A Nevada roulette wheel had 38 pockets, labeled as 0 00 1 2 3 ... 35 36. One bet is single number. If you bet $1 on a number (an

Answer:

-0.0526

Step-by-step explanation:

Let X be the random variable denoting the net gain(in dollars) for a single trial(one bet).

Assuming that each number in the wheel is equally likely, probability of the outcome being a victory is $\frac{1}{38}$ and probability of failure is $\frac{37}{38}$ . For a win, X takes value 35 and for a loss X takes value -1. So the model is,

$P(X=35) = \frac{1}{38}$

$P(X=-1) = \frac{37}{38}$

$P(X=i) = 0 \;if\; i \neq 38, i\neq -1$

The mean for one bet is $E(X) = \sum xP(X=x) = 35\times\frac{1}{38} - 1\times\frac{37}{38} = -0.0526$

nignag [31]

Answer:

Choice B & C

Step-by-step explanation:

563 - 192 = 371

The subtraction equals to 371.

100 + 90 + 210 = 400

The answer does not equal to 371 in choice A.

563 - 200 + 8 = 371

The answer equals to 371 in choice B.

571 - 200 = 371.

The answer equals to 371 in choice C.

Hey all you math geniuses can you help me with this question that should be easy

kenny6666 [7]

Answer:

(B) $\frac{-3}{x}$

Step-by-step explanation:

A polynomial is the expression which consists of addition, subtraction, multiplication with any variables or constants but the division with a variable is not considered as a polynomial.

Since $\frac{-3}{x}$ consists of division of -3 with a variable, therefore it is not a polynomial, rest all other options are polynomial as they involve addition,multiplication with variables.
