Answer:

x + 31 $\frac{1}{2}$

Step-by-step explanation:

P = x + 2/(21 - 2x) + x + 2/(21 - 2x) + x + 2/(21 - 2x) + x

= x + 21/2 - x + x + 21/2 - x + x + 21/2 - x + x

= x + 21/2 + 21/2 + 21/2

=x + 31 $\frac{1}{2}$

14) A carnival has set up the following game. You are blindfolded and have to pick a coin from 9 pennies, 8

zmey [24]

Using the expected value, it is found that you should be expected to win $0.0032 every time you play the game.

A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.

The expected value is given by the <u>sum of each value multiplied by it's respective probability</u>.

9 + 8 + 12 + 16 + 11 + 4 = 60

In total, there are 60 coins.

Considering the cost of $0.25, the probability of each monetary outcome when one coin is chosen is:

$P(X = -0.24) = \frac{9}{60}$

$P(X = -0.20) = \frac{8}{60}$

$P(X = -0.15) = \frac{12}{60}$

$P(X = 0) = \frac{16}{60}$

$P(X = 0.25) = \frac{11}{60}$

$P(X = 0.75) = \frac{4}{60}$

Hence, the expected value is:

$E(X) = -0.24\frac{9}{60} - 0.2\frac{8}{60} - 0.15\frac{12}{60} + 0\frac{16}{60} + 0.25\frac{11}{60} + 0.75\frac{4}{60}$

$E(X) = \frac{-0.24(9) - 0.2(8) - 0.15(12) + 0(16) + 0.25(11) + 0.75(4)}{60} = 0.0032$

You should be expected to win $0.0032 every time you play the game.
