Answer:

50 times.

Step-by-step explanation:

Since the two coins are fair, each has a 1/2 chance of landing on heads. If both of them land on heads, that possibility would be 1/4 (1/2 * 1/2)

Because you are running the experiment 200 times, multiply 200 by 1/4:

200/4 = 50 times.

Hope this helps!

I will give brainliest answer

Answer: A=351.68 cm²

Step-by-step explanation:

To find the area of the shaded region, we would subtract the area of the circle by the area of the inner circle.

Area of Circle

$A=\pi r^2$

$A=\pi (11)^2$

$A=121\pi$

Area of inner (white) circle

$A=\pi r^2$

$A=\pi (3)^2$

$A=9\pi$

Now that we have the area to the circle and inner circle, we would subtract to find the area of the shaded region.

$A=121\pi -9\pi$

$A=112\pi$

$A=351.68 cm^2$
