A coin is being flipped 400 times. What is the probability of it landing on heads at most 170 times, rounded to the nearest tent
h of a percent?
1 answer:
Hello!
We have two probabilities we can use; we have 170/400, for our experiment, and 1/2, which is our theoretical probability.
To solve, we just multiply the two probabilities.
=0.2125≈21.3
Therefore, we have about a 21.3% chance of this event occurring.
I hope this helps!
