A game involves selecting a card from a regular 52-card deck and tossing a coin. The coin is a fair coin and is equally likely t
barxatty [35]

Answer:

Expected net earning X for this case is \frac{18}{26} =$0.6923

Step-by-step explanation:

We need to calculate the probability of the case and multiply by the net earning. The Case is:

<u>the card is a Face card, and the coin lands on Heads</u><u>:</u>

<em>Net earning</em> = 9-3 =6

There are 12 Face Cards in a regular 52-card deck. Then,

<em>Probability  of a Face Card</em>= \frac{12}{52}

<em>Probability that the coin lands on Tails</em> = \frac{1}{2}

Then <em>total probability of the case</em> is = \frac{12}{52} × \frac{1}{2} =\frac{3}{26}

Expected net earning X for this case is = \frac{3}{26} × 6 = \frac{18}{26}

The total cost of a jacket and a pair of pants was $66.12. If the price of the jacket was $3.26 less than the pair of pants, wha
drek231 [11]

Answer:

The price of the jacket was $31.43

Step-by-step explanation:

Let the cost of a jacket = x

Let the cost of a pair of pants = y

Such that,

x + y = $66.12.........Equation 1.

From the conditional statement,

x = y - $3.26..........Equation 2.

Solve both equations simultaneously, using the substitution method

From Equation 2;

x = y - 3.26

Substitute y - 3.26 for x in Equation 1.

x + y = 66.12, now becomes,

y - 3.26 + y = 66.12

collect like terms

y + y = 66.12 + 3.26

2y = 69.36

y= 69.36/2 = $34.69.

Put y = $34.69 in Equation 2. to obtain x

x = 34.69 - 3.26

x = $31.43
