you flip a coin. what is p(heads or tails)? write your answer as a percentage rounded to the nearest tenth. %
Answer
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: Calculate P(heads or tails)
The number of favorable outcomes for the event "heads or tails" is $m=2$. So $P(\text{heads or tails})=\frac{2}{2}=1$.
Step3: Convert to percentage
To convert the probability to a percentage, we multiply by 100. So $1\times100 = 100%$.
Answer:
100%
