Sagot :

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
