To find the probability of getting one head and one tail when tossing two coins, we first need to consider all possible outcomes.
When two coins are tossed, the possible outcomes are:
- Head – Head (HH)
- Head – Tail (HT)
- Tail – Head (TH)
- Tail – Tail (TT)
So, the total number of outcomes is 4.
Now, we need to count the favorable outcomes for getting one head and one tail. The favorable outcomes are:
- Head – Tail (HT)
- Tail – Head (TH)
There are 2 favorable outcomes.
The probability of an event is calculated as:
Probability = (Number of Favorable Outcomes) / (Total Number of Outcomes)
Substituting the values we have:
Probability = 2 / 4 = 1 / 2
Thus, the probability of getting one head and one tail when tossing two coins is 1/2 or 50%.
