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:
<h3>The probability of winning</h3>
Only one of the 1000 selections can win.
So, the probability of winning is:
<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:
So, we have:
Hence, the expected earning is -$1.156

Step-by-step explanation:
To find the area of this entire shape, we must divide it into two rectangles.
The first rectangle is on the bottom of the shape, with a length of 8 cm and a width of 3 cm.
The second rectangle is on the top of the shape. The length is (8-5) cm and the height is (7-3) cm.
To find the area of the total shape, we must add the areas of the two rectangles. To find the area of the rectangle, we use the formula, A = l * w.
8 * 3 = 24 cm^2
3 * 4 = 12 cm^2
24 sq cm + 12 sq cm = 36 square centimeters.
Therefore, the area is 36 square centimeters. Hope this helps! :)
