Probability Model Legitimate

You are playing a game using this spinner. You get one spin on each turn. Find a complete probability model for one spin of the spinner.

• P(number ​3)=1/4, ​P(letter ​A)= 1/4

• P(number)=1/2​, ​P(letter ​Y)= 1/4

• P(letter)=1/2​, P(number)=1/2

• P(letter)=1/2​, ​P(number ​5)= 1/4

A number cube is weighted so that the faces​ 1, 2, or 3 are all twice as likely to occur as each of the faces labeled​ 4, 5, or 6. What statements must you add to ​P(1)=2/9​, ​P(2)=2/9​, ​P(3)=2/9 to make a complete probability​ model?

• P(4)=1/9​, ​P(5)=1/9​, ​P(6)= 1/9

• ​P(4)=1/9​, ​P(5)=1/9​, ​P(6)= 2/9

• P(4)=1/12​, ​P(5)=1/12​, ​P(6)= 1/4

• P(4)=1/4​, ​P(5)=1/4​, ​P(6)= 1/12
