Roulette is a casino game that involves players betting on where a ball will land on a spinning wheel. An American roulette wheel has 38 numbered slots — half of the slots from 1 to 36 are red and the other half are black. Slots 000 and 000000 are both green. Suppose that a player bets \$1 on the color red. If the ball lands in a red slot, the player gets their initial \$1 back plus a payout of \$1 If the ball doesn't land in a red slot, they lose their \$1 bet. Let X=the player's net gain from a \$1bet on a the color red. Here is the probability distribution of X: Win Lose \$1$-\$1−$1minus, dollar sign, 1 P(X), , 18, divided by, 38, 20, divided by, 38, end fraction Calculate the mean of X. You may round your answer to the nearest thousandth. E(X)= equals dollars

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
