Question

you flip a coin. what is p(tails)? write your answer as a percentage.

Explanation:

Step1: Identify total and favorable outcomes

A coin - flip has 2 possible outcomes (heads or tails), and 1 favorable outcome (tails).

Step2: Calculate probability

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(\text{tails})=\frac{1}{2}$.

Step3: Convert to percentage

To convert a fraction to a percentage, we multiply by 100. So $\frac{1}{2}\times100 = 50$.

Answer:

50%
