Answer
7/16
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)=$\frac{numberoffavorableoutcomes}{numberofpossibleotcomes}$
The green is 3 square units and the white is 4 square units. The green and white area is 7 square units 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(green or white)=$\frac{7}{16}$
