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

-2/5x+6=8 can you help me
ale4655 [162]
If you would like to solve the equation - 2/5 * x + 6 = 8, you can do this using the following steps:

- 2/5 * x + 6 = 8
- 2/5 * x = 8 - 6
- 2/5 * x = 2    /*(-5/2)
x = 2 * (- 5/2)
x = - 5

The correct result would be -5.

elena-14-01-66 [18.8K]

Answer:

Probability = \frac{1}{8}

Step-by-step explanation:

Given

Represent Boys with B and Girls with G

P(B) = \frac{1}{2}

P(G) = \frac{1}{2}

Required

Find the probability or having 1 boy 2 girls

Since the order is not important, the probability is calculated as follows;

Probability = P(B) * P(G) * P(G)

Substitute \frac{1}{2} for P(B) and P(G)

Probability = \frac{1}{2} * \frac{1}{2} * \frac{1}{2}

Probability = \frac{1 * 1 * 1}{2 * 2 *2}

Probability = \frac{1}{8}

<em>Hence, the fractional probability is </em>\frac{1}{8}<em></em>
