Tossing Two Coins

When two coins are tossed simultaneously, there are four possible outcomes:
1. Both coins show heads (HH)
2. Both coins show tails (TT)
3. One coin shows heads and the other shows tails (HT)
4. One coin shows tails and the other shows heads (TH)

Probability of Getting Exactly One Head

To find the probability of getting exactly one head, we need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.

Favorable Outcomes
In this case, we are interested in the outcomes where we get exactly one head. There are two such outcomes: HT and TH.

Total Possible Outcomes
As mentioned earlier, there are four possible outcomes when tossing two coins: HH, TT, HT, and TH.

Calculating the Probability
To calculate the probability of getting exactly one head, we divide the number of favorable outcomes by the total number of possible outcomes.

Probability = (Number of Favorable Outcomes) / (Total Number of Possible Outcomes)

In this case:
Number of Favorable Outcomes = 2
Total Number of Possible Outcomes = 4

Probability = 2/4 = 1/2 = 0.5

Therefore, the probability of getting exactly one head when two coins are tossed simultaneously is 0.5 or 50%.

Summary
When two coins are tossed simultaneously, there are four possible outcomes: HH, TT, HT, and TH. The probability of getting exactly one head can be calculated by dividing the number of favorable outcomes (2) by the total number of possible outcomes (4). In this case, the probability is 0.5 or 50%.
