Answer:

E.G=\$2

Step-by-step explanation:

Sample size 52 card

Pay for J or Q =\$17

Pay for King or Ace =\$5

Pay for others =-\$2

Therefore

Probability of drawing J or Q

P(J&Q)=\frac{8}{52}

Probability or drawing King or Ace

P(K or A)=\frac{8}{52}

Probability or drawing Other cards

P(O)=\frac{36}{52}

Therefore

Expected Gain is mathematically given as

E.G=\sum_xP(x)

E.G=17*\frac{8}{52}+5*\frac{8}{52}+(-2)*\frac{36}{52}

E.G=\$2
