Answer: Option C

P=\frac{1}{3}

Step-by-step explanation:

We have a three section spinner and we want to know what is the probability of spinning the spinner twice and getting the same number.

The tree diagram shows that by spinning the spinner 2 times there are 9 possible results

S = \{(1, 1), (1, 2), (1, 3), (2, 1), (2, 2), (2, 3), (3, 1), (3, 2) , (3, 3)\}

Note that among these 9 possible outcomes there are 3 ways to get the same number

\{(1, 1), (2, 2), (3, 3)\}

Then the definition of probability tells us that:

P = \frac{number\ of\ desired\ outcomes}{possible\ outcomes}

In this case

number\ of\ desired\ outcomes = 3

possible\ outcomes =9

Finally

P=\frac{3}{9}

P=\frac{1}{3}

Answer:

I think it would be 1/9

Step-by-step explanation:

The probability of getting one specific number the first time is 1/3, and the next spin is also 1/3, and you have to multiply them.

Please help me I don’t know how to solve it and will mark brainiliest
Sindrei [870]

Answer: One plain roll is 4 dollars and one shiny roll is 6 dollars.

Step-by-step explanation:

lets start by saying

rolls of plain wrapping paper = x

rolls of shiny wrapping paper = y

Kathryn sold 4 plain rolls and 3 shiny rolls for 34 dollars.

4x+3y=34

Eugene sold 4 plain rolls and 2 shiny rolls for 28 dollars

4x+2y=28

Both equations will look like this.

4x+3y=34

-1(4x+2y)=(28)-1

we can multiply the second equation by -1 to get y alone. (doesn't matter which equation). Once you do that, the positive 4x and the negative 4x cancel out, 3y-2y=1y and 34-28=6. you are left with

1y=6 so one shiny roll is 6 dollars.

now use that price to find the cost of the plain roll.

lets use Kathryn's equation

4x + 3(6)=34

4x + 18= 34

      -18  -18

4x=16. Divide by 4 to find cost of one plain roll.

16÷4=4. One plain roll costs 4 dollars.

Lets check. Using Kathryn's equation,

4(4) + 3(6)=34

16+18=34

34=34. We are right.
