Holly took a 1900 km trip, travelling by bus and plane. The bus averaged 60 kn/h and the plane averaged 700 kn/h. If the total trip took 5 h, how many kilometres did she travel by bus?

If there are 14 different scenarios that can happen (Blue 1-5, Green 1-6, Red 1-3), and 9 of them are not blue, there is a 9/14 chance that the first pick is not blue. to get percentages, you divide 9 by 14 to get 0.64, or 64 percent chance at not picking blue.
