If you toss a fair coin 3 times, what is the probability of getting all heads?
The probability of getting a head on any single coin toss is 1/2, since there are two equally likely outcomes (heads or tails).
Since the coin tosses are independent events (the outcome of one does not affect the outcome of another), the probability of getting all heads on three coin tosses can be found by multiplying the probabilities of getting a head on each individual toss:
P(all heads) = (1/2) * (1/2) * (1/2) = 1/8
Therefore, the probability of getting all heads on three coin tosses is 1/8 or 0.125.
