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!
