A coin is tossed three times. What is the probability of tossing three heads in a row?
To find the probability of tossing three heads in a row, we need to know the probability of getting a head on each individual toss.
Since there are two possible outcomes when tossing a coin (heads or tails) and assuming the coin is fair, the probability of getting a head on one toss is 1/2.
Since each toss is independent of the others, we can multiply the probabilities together to find the probability of getting three heads in a row:
(1/2) * (1/2) * (1/2) = 1/8
So, the probability of tossing three heads in a row is 1/8 or 0.125, which is 12.5%.
To find the probability of tossing three heads in a row, we need to determine the total number of possible outcomes and the number of favorable outcomes.
In this case, when a coin is tossed three times, each toss has two possible outcomes – either heads (H) or tails (T). So, the total number of possible outcomes is 2 * 2 * 2 = 8.
Out of these 8 possible outcomes, there is only one outcome where all three tosses result in heads, which is HHH.
Therefore, the probability of tossing three heads in a row is 1 out of 8, which can be simplified to 1/8 or approximately 0.125.
