Which graph correctly displays the probability distribution for this
spinner's results?

Answer 1

Answer: Graph A shows the correct probability distribution.

Explanation:

The probability of the spinner landing on "A" is 1/2. Similarly, the probability of the spinner landing on "B" is 3/8. Therefore, the probability of the spinner landing on "C" is 1-1/2-3/8=1/8. So:

probability of landing on "A" is 1/2 = 0.5,

probability of landing on "B" is 3/8 = 0.375, and

probability of landing on "C" is 1/8 = 0.125.

Thus the correct probability distribution should be answer choice
`\boxed{\text{A}}.`
