We have that in a deck of cards, there are 3 kinds of cards that have value under 4 (or equal). These are 2,3,4 and they are in total 4*3=12. The probability that we draw such a card is 12/52=0.23. Hence the probability that we do not draw such a card is 1-0.23=0.77. If we play the game once, we will get 0.23 of the times 37$ and 0.77 of the times 15$. Hence, the net total expected outcome is: 0.23*37$-0.77*15$=-3.001$. After playing this game for 713 times, we will lose in total: 713*3.001$=2139.74$. The losses will be - 2139.74$
