**Answer:**

**probability that the arrow will stop on the same letter twice = (c).**

**Step-by-step explanation:**

Given : Maria will spin the arrow on the spinner 2 times.

To find : What is the probability that the arrow will stop on the same letter twice.

Solution : We have given a spinner that spin twice and stop on the same letter.

Formula for probability = .

Here, total part of spinner = 3 and it spin two times

So, total possible outcome = 6. Arrow ston on same letter twice( favorable outcome) =2.

Plugging the values in formula :

Probability = .

Probability = .

**Therefore, probability that the arrow will stop on the same letter twice = (c).**

So, we need to add 3/4 + 2 1/6.

First, let's find a common denominator.

12 is one.

4 x 3 = 12 3 x 3 = 9 6 x 2 = 12 1 x 2 = 2 2/12 & 9/12 = 11/12

2 + 0 = 2. 2 + 11/12 = 2 11/12.

**2 11/12 is your answer.**

It is .277

because there are 26 letters in the alphabet, and 10 numbers given (0-9)

add both amount of characters: 26+10=36

then put a number of numbers over the total amount of characters: 10/36

now divide 10 by 36

and you will get .277777, but since you said by the nearest hundredth, estimate and get

QUESTION POSTED AT 28/03/2020 - 11:40 AM

I guess this cube is a dye & it has six faces numbered from 1 to 6.

If so the expected value is the probability x number of times:

P(getting 1 or 2 or 3 or 4) = 4/6 = 2/3

The number of times = 10, hence the expected value is 12x(2/3) = 8 times

If so the expected value is the probability x number of times:

P(getting 1 or 2 or 3 or 4) = 4/6 = 2/3
