Question

Suppose that you and a friend are playing cards and you decide to make a friendly wager. The bet is that you will draw two cards without

replacement from a standard deck. If both cards are hearts, your friend will pay you $35. Otherwise, you have to pay your friend $5.
Step 1 of 2: What is the expected value of your bet? Round your answer to two decimal places. Losses must be expressed as negative values.

Answer 1

`-2.65`

Explanation:

`x\\\\ P(x)`
`35\\ \\ (156)/(2652)`
`-5\\\\(2496)/(2652)`

`E(x)=(156)/(2652)*35-(2496)/(2652)*5\\ =-2.65`
