%

Answer 1

When flipping a fair coin, there are two possible outcomes: heads or tails.

The probability of getting heads (P(heads)) is 0.5, and the probability of getting tails (P(tails)) is also 0.5.

To find the probability of getting either tails or heads, we add the probabilities of the two mutually exclusive outcomes:

\[ P(tails \text{ or } heads) = P(tails) + P(heads) = 0.5 + 0.5 = 1.0 \]

To convert this probability into a percentage, we multiply by 100:

\[ 1.0 \times 100 = 100\% \]

So, the answer is:

**100.0%**
