Q: If two coins are tossed, what is the probability of getting at least one tail? (2023)
Solution: The possible outcomes are HH, HT, TH, TT. The outcomes with at least one tail are HT, TH, TT (3 outcomes). So, the probability is 3/4.
Steps: 7
Step 1: Understand that we are tossing two coins.
Step 2: List all possible outcomes when tossing two coins. The outcomes are: HH (both heads), HT (first head, second tail), TH (first tail, second head), TT (both tails).
Step 3: Count the total number of outcomes. There are 4 outcomes: HH, HT, TH, TT.
Step 4: Identify which outcomes have at least one tail. The outcomes with at least one tail are HT, TH, and TT.
Step 5: Count the number of outcomes with at least one tail. There are 3 outcomes: HT, TH, TT.
Step 6: Calculate the probability of getting at least one tail. The probability is the number of favorable outcomes (3) divided by the total number of outcomes (4).
