Answer
5/8
Work Step by Step
Find the area of each region:
White area=4 square units
Red area=3 square units
Blue area=6 square units
Green area=3 square units
Total area=16 square units
P(events)=$\frac{favorableoutcomes}{possibleoutcomes}$
You have to find the ones which are not blue, so you subtract the total area and the blue area:16-6-10. The rest of the areas are 10 so it is the number of favorable outcomes. The area is 16 square units in total so this is the number of possible outcomes.
P(blue)=$\frac{10}{16}$ -simplify-
p(blue)=$\frac{5}{8}$
