Answer:
2/3
Step-by-step explanation:
So the probability would be what you're finding divided by the total amount. For example, if you were finding P(blue) then it would be 6/18, which is 1/3.
Not blue would be Total - Blue, so:
(6 + 5 + 4 + 3) - 6
18 - 6
12
There are 12 that are not blue, so:
P(Not Blue) = NotBlue/Total
= 12/18
= 2/3
