You are challenged to a lucky draw game. If you draw a face card (K, Q, J) from a standard deck of cards, you earn 10 points. If

Aleksandr [31]

The Expected value of a draw from the given question is; A; 0.77

We are told the face cards are K, Q, J. This means that there are 3 face cards for each of the 4 suits.

Since you earn 10 points for each face card, it means that;

total possible gain = 10 × 3 × 4 = 120

In a deck of cards, there are a total of 52 cards.

This means that;

Number of cards that are not K, Q or J = 52 - (4 × 3) = 40

Since 2 points are lost for drawing any of this 40 cards, then;

Total possible loss = 40 × 2 = 80

Expected gain = 120 - 80

Expected gain = 40

Expected value of a draw = 40/52

Expected value of a draw = 0.77

common ratio = 2nd term ÷ first term

= 12 ÷ 3

r = 4

$a_{n} = ar^{n-1}\\\\a_{10}=3*4^{9}\\\\\\ = 3 * 262144\\\\= 786432$

At the farmers market two pounds of peaches cost 4.20 how much would five pounds cost show work

Marizza181 [45]

Hey!

You can make a proportion:

$\frac{2}{\$ 4.20} = \frac{5}{x}$

Cross multiply

$\$ 4.20 \times 5 = \$ 21$

Divide by 2

$\$ 21 \div 2 = \$ 10.5$

<em>5 pounds would cost $10.50</em>

Good luck and hope this helps! :)
