If spiner has 3 equal sections of yellow, blue and green and another has equal sections of yellow, blue, green and red and you spin both spinners at the same time what is the probabiliy of getting 2 colors that are the same?

there are 12 different arrangements of colour,
e.g. YY,YB,YG,YR, BY,BB, ....
3 of those have the same colour,
so prob = 3/12 or 1/4
