Question

you flip a coin. what is p(not heads)? write your answer as a fraction or whole number. submit

Explanation:

Step1: Determine total outcomes

A coin has 2 sides (heads and tails). So total outcomes \( n(S)=2 \).

Step2: Determine favorable outcomes for 'not heads'

'Not heads' means tails. Number of favorable outcomes \( n(E) = 1 \).

Step3: Use probability formula

Probability \( P(E)=\frac{n(E)}{n(S)} \). Substituting values, \( P(\text{not heads})=\frac{1}{2} \).

Answer:

\(\frac{1}{2}\)
