    Roll
In summary, the conversation discusses a game where paying \$2 gives the player a chance to win \$10 by rolling a one on a balanced die. The two possibilities for the game are winning \$10 or losing \$2, with a probability of 1/6 for rolling a one. The expected value of the game is discussed and the question is posed whether one would pay \$2 to play.

Welcome to MHB lilly! :)

The two possibilities are that either you win \$10 or you lose \$2.

A balanced die is a die with 6 sides that each have the same probability of coming up.
So the probability on a one is 1/6.

How much do you think you would earn if you play this game?
This is called "expected value".
To find it you need to multiply the probabilities with the outcomes and add them up.
What do you think it is?

How is the game "Roll the Die: Win $10 or Lose $2" related to probability and expected value?

This game is related to probability because it involves calculating the likelihood of certain outcomes occurring. The expected value in this game is calculated by multiplying the probabilities of winning and losing by the corresponding payouts and then subtracting the losing outcomes from the winning outcomes. In this case, the expected value is ($10 x 4/6) - ($2 x 2/6) = $2.67, meaning that on average, the player can expect to win $2.67 per roll.
