I really need help!!!
A spinner is divided into 4 sectors of equal size, with the sectors numbered 1 through 4. The probability of the spinner landing on a given sector is the same for all the sectors. The spinner is spun twice, and the results of the spins are added together.

What is the expected value of the sum of the 2 results?

Answer:

1/2

Step-by-step explanation:

If a spinner is divided into quarters, one section would be 1/4. So, if you spin twice you would get, 1/4 + 1/4 = 2/4 = 1/2

So, your answer would be 1/2
