Suppose you have a weighted coin in which heads comes up with probability 3/4 and tails with probability 1/4. If you flip heads, you win $2 but if you flip tails, you lose $1 What is the expected win of a coin flip in dollars?
You know you can ask question on bartleby.com
So 3/4 of the time, you win 2, and 1/4 of the time, you win -1.
3/4*2 = 6/4
1/4 * -1 = -1/4
6/4 - 1/4 = 5/4
Hopefully that's the answer. :))
