(adapted from Ross, 2.31) Three countries (the Land of Fire, the Land of Wind, and the Land of Earth) each make a 3 person team. Each team consists of three ninjas, each of a different rank: one genin junior ninja, one journeyman ninja, and one elite ninja.

(a) If a ninja is chosen at random from each of the three different countries, what is the probability of selecting a complete team? (A complete team here is a group consisting of three ninjas, each ninja of a different rank).

(b) If a ninja is chosen at random from each of the three different countries, what is the probability that all 3 ninjas selected have the same rank?

Answers

Answer 1

Answer:

The answer is "[tex]\frac{2}{9} \ and \ \frac{1}{9}[/tex]"

Step-by-step explanation:

In point a:

The requires  1 genin, 1 chunin , and 1 jonin to shape a complete team but we all recognize that each nation's team is comprised of 1 genin, 1 chunin, and 1 jonin.

They can now pick 1 genin from a certain matter of national with the value:

[tex]\frac{1}{\binom{3}{1}}=\frac{1}{3} .[/tex]

They can pick 1 Chunin form of the matter of national with the value:

[tex]\frac{1}{\binom{3}{1}}=\frac{1}{3} .[/tex]

They have the option to pick 1 join from of the country team with such a probability: [tex]\frac{1}{\binom{3}{1}}=\frac{1}{3}[/tex]

And we can make the country teams: [tex]3! = 6[/tex] different forms. Its chances of choosing a team full in the process described also are:

[tex]6 \times \frac{1}{3}\times \frac{1}{3}\times \frac{1}{3}=\frac{2}{9}.[/tex]

In point b:

In this scenario, one of the 3 professional sides can either choose 3 genins or 3 chunines or 3 joniners. So, that we can form three groups that contain the same ninjas (either 3 genin or 3 chunin or 3 jonin).

Its likelihood that even a specific nation team ninja would be chosen is now: [tex]\frac{1}{\binom{3}{1}}=\frac{1}{3}[/tex]

Its odds of choosing the same rank ninja in such a different country team are: [tex]\frac{1}{\binom{3}{1}}=\frac{1}{3}[/tex]

The likelihood of choosing the same level Ninja from the residual matter of national is: [tex]\frac{1}{\binom{3}{1}}=\frac{1}{3}[/tex] Therefore, all 3 selected ninjas are likely the same grade: [tex]3\times \frac{1}{3}\times \frac{1}{3}\times \frac{1}{3}=\frac{1}{9}[/tex]

Dan rolls a fair dice and flips a fair coin. What is the probability of obtaining an even number and a head

Answers

Answer: 1/4

Step-by-step explanation:

A die has 6 figures which are 1, 2, 3, 4, 5 and 6. There are 3 even numbers which are 2, 4 and 6. A coin has 2 outcomes which are head or tail.

The probability of getting an even number is 3/6 = 1/2.

The probability of getting a head is 1/2.

Therefore, the probability of obtaining an even number and a head will be:

It costs $3.75 to buy 3/4 of a pound of walnuts how many pounds of walnuts can you purchase with 11.25

Answers

Answer: 2.25 or 2  1/4 pound of walnut

Step-by-step explanation: So here you need to figure out how many pound of walnut can you purchase with 1 dollar first. To do that, you need to -- 3.75 ÷ 3/4 which you can convert to 3.75 ÷ 0.75 and the answer would be 5.

Now if you do this -- 11.25 ÷ 5 = 2.25

So the answer is 2.25 or 2 and 1/4 pound of walnut

Pounds of his weight that is made up of fat is calculated as

Body fat percentage × Body weight in pounds

Write an algebraic expression to model the given context. Give your answer in simplest form. the price p of a coat reduced by a 5% discount​

Answers

Answer:

We conclude that the expression of the price p of a coat reduced by a 5% discount​ will be: 0.95 p      

Step-by-step explanation:

Let 'p' be the original price

Discount = 5% = 0.05

The discount amount can be calculated by multiplying the original price by 5% or 0.05

Discount Amount = 5% × p

                             = 0.05 × p

                             = 0.05 p

Given that the price p of a coat reduced by a 5% discount​.

Thus, the price after 5% discount​ can be calculated by subtracting the discount amount i.e. 0.05 p from the original price p.

Thus,

The expression of the price p after 5% discount​ = p - 0.05 p

                                                                                = 0.95 p

Therefore, we conclude that the expression of the price p of a coat reduced by a 5% discount​ will be: 0.95 p

Which is a correct classification for the triangle?
O equiangular triangle
O right triangle
O acute triangle
O obtuse triangle

Answers

Answer:

right angle

Step-by-step explanation:

180-(31+59)= 90

The correct classification of the triangle should be considered as the right triangle.

What is the right triangle?

A right triangle or right-angled triangle, or more formally an orthogonal triangle, formerly called a rectangled triangle, is a triangle in which one angle is a right angle, i.e., in which two sides are perpendicular. The relation between the sides and other angles of the right triangle is the basis for trigonometry.

here, we have,

given that,

In the case when the sum the two given angles is 90,

so, the other angle will be 90

so, its a right triangle.

A right angled triangle is a triangle in which one of the angles is 90°. A 90-degree angle is called a right angle, and hence the triangle with a right angle is called a right triangle. Further, based on the other angle values, the right triangles are classified as isosceles right triangles and scalene right triangles.

Hence, The correct classification of the triangle should be considered as the right triangle.
