You and a friend play a game where you each toss a balanced coin. If the upper faces on the coins are both tails, you win $8; if the faces are both heads, you win $4; if the coins do not match (one shows a head, the other a tail), you lose $2 (win (−$2)). Calculate the mean and variance of Y, your winnings on a single play of the game. Note that E(Y) > 0.

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

all it means is function 3

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
