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

Explanation:

Step1: Recall probability formula

The probability of an event $E$ is $P(E)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. When flipping a coin, the total number of possible outcomes is $n = 2$ (heads or tails).

Step2: Determine favorable outcomes

The event of getting heads or tails has $m=2$ favorable outcomes (either heads or tails).

Step3: Calculate the probability

Using the formula $P=\frac{m}{n}$, we substitute $m = 2$ and $n=2$, so $P=\frac{2}{2}=1$.

Answer:

$1$
