alexgriva [62]

Answer:

The answer should be 2

Step-by-step explanation:

16 pi = 1/3 pi r^2 ( 12) Divide both sides by pi

In a state's Pick 3 lottery game, you pay $1.42 to select a sequence of three digits (from 0 to 9), such as 966. If you select t

Mumz [18]

The lottery game is an illustration of probability

The total number of different selections is 1000
The probability of winning is 0.001
The net profit of winning is $262.82
The expected earning is -$1.156

<h3>The number of selections</h3>

Each of the three selections can be any of the 1o digits 0 - 9.

So, the total number of different selections is:

$n = 10^3$

$n = 1000$

<h3>The probability of winning</h3>

Only one of the 1000 selections can win.

So, the probability of winning is:

$p = \frac 1{1000}$

$p = 0.001$

<h3>The net profit</h3>

The stake amount is given as $1.42, and the earnings per game is given as $264.25.

So, the net profit is:

Net = $264.25 - $1.42

Net = $262.82

<h3>The expected winnings</h3>

This is calculated as:

$E(x) = \sum x P(x)$

So, we have:

$E(x) = 262.82 * 0.001 - 1.42 * (1 - 0.001)$

$E(x) = -1.156$

Hence, the expected earning is -$1.156

Alchen [17]

Remember the notation..

When you have a triangle called ABD, the angles may be called in theses equivalent ways>

angle A is equivalent to ∠ DAB
angle B is equivalent to ∠ ABD
angle D is equivalen to ∠ BDA

Then given that the two triangles are congruent, you can say an

angle B = angle F = ∠ EFC
