The figure below shows a shaded circular region inside a larger circle:
A shaded circle is shown inside another larger circle. The radius of the smaller circle is labeled as r and the radius of the larger circle is labeled as R. On the right side of the image is written r equal to 3 inches and below r equal to 3 inches is written R equal to 5 inches.
What is the probability that a point chosen inside the larger circle is not in the shaded region?
24%
36%
50%
64%

100 [ 25 pi - 9 pi ] / 25 pi = 100 (16/25) = 4*16 = 64%
thank you so much
i have 2 more questions:
Stephen has a counter that is orange on one side and brown on the other. The counter is shown below:
A circular counter is shown. The top surface of the counter is shaded in a lighter shade of gray and Orange is written across this section. The bottom section of the counter is shaded in darker shade of gray and Brown is written across it.
Stephen flips this counter 24 times. What is the probability that the 25th flip will result in the counter landing on orange side up?

1 cm = 8 ft
so
divide feet by 8 to get cm
32ft by 48ft is 4 cm by 6 cm
so
divide feet by 8 to get cm
32ft by 48ft is 4 cm by 6 cm
