A box is filled with 6 red cards, 8 green cards and 4 blue cards what is the probability that the card is not green that is chosen

5/9

Step-by-step explanation:

6 red cards, 8 green cards and 4 blue cards =  18 total cards

not green cards = 6 red+ 4 blue = 10 cards

P( not green) = number not green / total

                      = 10/18

                      =5/9

360 different combinations

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
