Question

Alice spins the spinner 2 times. What is the probability that the spinner stops on A and then B, or on B and then A? 19 29 13 59

Answer 1

i just took the test on k12 and the answer is 2/9

** do not simplify it

Answer 2

Answer with explanation:

Number of section on the Spinner = A or B or Neither A nor B.⇒Total favorable Outcome

Probability of Spinner spinning on either of three section

`=\frac{\text{Total favorable outcome}}{\text{Total possible outcome}}\\\\=(1)/(3)`

Probability that the spinner stops on A and then B, or on B and then A

`\\\\=P(A)*P(B)+P(B)*P(A)\\\\=(1)/(3)*(1)/(3)+(1)/(3)*(1)/(3)\\\\=(1)/(9)+(1)/(9)\\\\=(2)/(9)`

Option B:
`(2)/(9)`
