Question

you flip a coin. what is p(tails or heads)? simplify your answer and write it as a fraction or whole number.

Explanation:

Step1: Identify possible outcomes

When flipping a coin, the possible outcomes are heads (H) and tails (T), so there are 2 possible outcomes.

Step2: Identify favorable outcomes

We want the probability of getting tails or heads. Since these are the only two possible outcomes, the number of favorable outcomes (tails or heads) is also 2.

Step3: Calculate probability

The probability \( P(\text{event}) \) is given by the formula \( P(\text{event})=\frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}} \).
For \( P(\text{tails or heads}) \), the number of favorable outcomes is 2 and the total number of possible outcomes is 2. So \( P(\text{tails or heads})=\frac{2}{2} = 1 \).

Answer:

\( 1 \)
