A coin is flipped 4 times. What is the probability of getting at least 1 tail? (Enter your probability as a fraction.)
The probability of getting at least 1 tail in 4 coin flips can be calculated by finding the probability of getting all heads and subtracting it from 1.
The probability of getting all heads in 4 flips is (1/2)^4 = 1/16.
So, the probability of getting at least 1 tail is 1 - 1/16 = 15/16.
Therefore, the probability of getting at least 1 tail in 4 coin flips is 15/16.
