Step-by-step explanation:
if 900 is increased by 20% then
120/100×900=1080
Decreasing it by 20% then
80/100×1080=864
So 6^2 would be 36 because it is 6 times 6 and then -4 so 36-4=32
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.
