you flip a coin. what is p(not tails)? write your answer as a percentage. %
Answer
Explanation:
Step1: Identify total and favorable outcomes
A coin - flip has 2 possible outcomes (heads or tails). 'Not tails' means heads, so there is 1 favorable outcome.
Step2: Calculate probability
The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. Here, $P(\text{not tails})=\frac{1}{2}$.
Step3: Convert to percentage
To convert a fraction to a percentage, we use the formula $\text{Percentage}=P\times100%$. So, $\frac{1}{2}\times100% = 50%$.
Answer:
50%
