Question

you flip a coin. what is p(heads)? write your answer as a percentage rounded to the nearest tenth.

Explanation:

Step1: Identify total outcomes

A coin has 2 sides (heads and tails), so total outcomes = 2.

Step2: Identify favorable outcomes

The favorable outcome of getting heads is 1.

Step3: Calculate probability

The probability formula is $P=\frac{\text{favorable outcomes}}{\text{total outcomes}}$. So $P(\text{heads})=\frac{1}{2}$.

Step4: Convert to percentage

$\frac{1}{2}=0.5$, and $0.5\times100 = 50.0\%$.

Answer:

50.0%
