Three coins are tossed in succession. What is the probability of heads-tails-heads?
To find the probability of a specific outcome in a coin toss experiment, we need to determine the total number of possible outcomes and the number of favorable outcomes
To find the probability of a specific outcome in a coin toss experiment, we need to determine the total number of possible outcomes and the number of favorable outcomes.
In this case, we are interested in the probability of getting heads-tails-heads. Each coin toss has 2 possible outcomes, either heads (H) or tails (T). Therefore, the total number of possible outcomes for three coin tosses is 2 * 2 * 2 = 8.
Now, let’s determine the number of favorable outcomes. In order to get heads-tails-heads, the first coin must land on heads, the second coin must land on tails, and the third coin must land on heads. This gives us only 1 favorable outcome.
So, the probability of getting heads-tails-heads is:
Number of favorable outcomes / Total number of possible outcomes
Probability = 1/8
Therefore, the probability of getting heads-tails-heads in three coin tosses is 1/8 or 0.125.
