A game is played by flipping three coins. If all three coins lands heads up you win $15. If two coins lands heads up you win $5. If one coin lands heads up you win $2. If no coin land heads up you win nothing. If you pay $4 to play, what are your expected winnings?
-------------
Random winning values::::::: 11::::1::::-2
-------------
Corresponding probabilities: 1/8:::3/8:::3/8
===============
Expected winnings = (1/8)(11) + (3/8)*1 + (3/8)(-2)
=[11 + 3 -6]/8
=[8/8]
= $1
