no both if you look at it first red than yello so 3/12 + 3/12 so 6/12 = 1/2

I am not sure what it is asking

Answer 18

1/2 is correct

Answer 19

because it is 3/12 if it lands on red, and 3/12 if it lands on yellow, so I guess 1/2 would be correct

A and B are mutually exclusive so P(A or B)=P(A)+P(B)
