Picture?? This question is incomplete just get a picture then I can answer it
The degree of vertex b is b
The probability of spinning on yellow would be 1/3 because this is broken into 3 pieces and that would be the probability of something that has been broken into 3 pieces, and 1/3 in decimal form would be 0.33.
The probability of spinning a blue would be 1/2 because the blue is broken into 1/2 of the spinner, therefore the probability of spinning a blue would be 1/2, and 1/2 in decimal form would be 0.5.
Therefore your answers are,
Blue=0.5
Yellow=0.33
Concentric circles because if a line is tangent to one circle, it would only intersect teh other
