Jinning is going to flip a coin. If the result is “heads,” he wins
What is his expected value per flip?
What is the probability of landing on "heads"?
How about the probability of landing on "tails"?
Multiply each $ outcome by its probability of occurring then find the sum.
If he flips the coin
times, about how much should he expect to win (or lose)?
If your answer for part (a) is the expected value for one flip, then what is the value for 8 of those flips combined?
