what is the probability that a quarter lands on heads 4 times in a row?
The probability of a quarter landing on heads is 0.5 (assuming the coin is fair).
To calculate the probability of getting heads 4 times in a row, you would need to multiply the probability of getting heads each time.
So, the probability of getting heads 4 times in a row is:
0.5 * 0.5 * 0.5 * 0.5 = 0.0625
Therefore, the probability of a quarter landing on heads 4 times in a row is 0.0625 or 6.25%.
