Did you know that all 50 states in the United States have some sort of state fair? Fairs and carnivals
include a variety of games of chance that aren't typically "fair." What does it mean for a game to be fair? In
this task, you'll analyze different scenarios to determine fairness. You will use probability and expected
value to make these determinations. You will also use these concepts to make decisions.
As you complete the assignment, keep this question in mind:

Tanya should play The second game to win more.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
Given, Tanya is considering playing a game at the fair. There are three different ones to choose from, and it costs $2 to play a game. The probabilities associated with the games are given in the table.
From the general formula of weighted possibility :
Total weighted possibility = Sum of the weighted probability of desired outcomes - the weighted possibility of undesired outcomes
In our case,
For first game
The sum of the weighted possibility of desired outcomes = 0.20*1 + 0.25 *4
The sum of the weighted possibility of desired outcomes = 1.20
the weighted possibility of undesired outcomes = 0.55 * 2 = 1.10
Thus,
Total weighted desired possibility = 1.20 - 1.10
Total weighted desired possibility = 0.10
For second game
The sum of the weighted possibility of desired outcomes =0.35*1 + 0.50 *4
The sum of the weighted possibility of desired outcomes = 2.35
the weighted possibility of undesired outcomes = 0.15 * 2 = 0.30
Thus,
Total weighted desired possibility = 2.35 - 0.30
Total weighted desired possibility = 2.05
For third game
The sum of the weighted possibility of desired outcomes = 0.60*1 + 0.20*4
The sum of the weighted possibility of desired outcomes = 1.40
the weighted possibility of undesired outcomes = 0.20 * 2 = 0.40
Thus,
Total weighted desired possibility =1.40 - 0.40
Total weighted desired possibility = 1
Therefore, Tanya should play The second game to win more.

Angles A and B are complementary. The measure of angle A
is yº. What is the measure of angle B?
Answers
Answer:
D, [tex](90-y)[/tex] degrees
Step-by-step explanation:
Complementary angles are angles that add up to 90 degrees. Since angle A and angle B are complementary, they add up to 90. Since the value of angle A is y degrees, we can substitute y into the equation to get
[tex]y+B=90[/tex]
To get the measure of angle B, we must isolate B.
To isolate B, we have to remove every term from its side.
The only term on the side that B is on other than B is y. To remove y from the left side, we must subtract y from both sides. Doing this will result in the equation:
[tex]B=90-y[/tex]
The only answer option that meets this criteria is D.

Answers
Answer:
the original population of the city is 7,505,833
Step-by-step explanation:
Given;
new of the population of the city, Y = 9,007,000
the percentage increase of the city, = 20% = 0.2
Let the original population of the city = X
New population, Y = X + 0.2X
Y = X(1 + 0.2)
Y = X(1.2)
Y = 1.2X
X = Y/1.2
X = (9,007,000) / 1.2
X = 7,505,833
Therefore the original population of the city is 7,505,833

if you have a cylindrical tank that's 10 feet long and has a radius of 2 feet, what's the maximum possible capacity of the tank in gallons of water if 1 cubic foot of water = 7.48 gallons? Round your answer to two decimal places.
Answers
Answer:
Step-by-step explanation:
Volume = pi * r^2 * h
r = 2 feet
h = 10 feet
Volume = 3.14 * 2^2 * 10
Volume = 125.6 cubic feet
1 cubic foot contains 7.48 gallons
125.6 cubic feet contain 7.48 * 125.6 = 930.488
The tank contains 930.49 gallons.

HELLLPPP 31 kilograms is the same as how many pounds? Hint: 1 kg = 2.2 lb Round your answer to the nearest tenth.
Answers
Hi! I'm happy to help!
To solve this, we need to turn all the kilograms into pounds. We know that to turn 1 kg into a pound, you multiply the amount of kilograms by 2.2.
Knowing this, we can multiply our 31 kilograms by 2.2.
31×2.2=68.2
This means that 31 kilograms is equal to 68.2 pounds.

Answer:
y = 5/6x + 8/3
Step-by-step explanation:
y = mx + b (m is the slope, b is the y-intercept)
(-2, 1) (4, 6)
m = change in y / change in x
m = 5/6
y = 5/6x + b
Plugging in (4, 6):
6 = 5/6(4) + b
6 = 20/6 + b
36/6 = 20/6 + b
36/6 - 20/6 = b
b = 16/6
b = 8/3
y = 5/6x + 8/3
