What is the expectation? How does it work?

I will flip two coins. If both coins come up tails, I will pay you $6. If one shows heads and one shows tails, you will pay me $2. If both coins come up heads, we will call it a draw. What is your expectation (in dollars) for this game?

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?

Do you have answers choice but i think the answer is 18 because 2/3 times 18 =12 serving hope this can i have brinlyest
