Question

you flip a coin.
what is p(not heads)?
write your answer as a percentage.
%

Explanation:

Step1: Determine the total number of outcomes

When flipping a coin, there are 2 possible outcomes: heads (H) or tails (T). So, \(n = 2\).

Step2: Determine the number of favorable outcomes for "not heads"

The event "not heads" means getting tails. The number of favorable outcomes for tails is \(m=1\).

Step3: Calculate the probability as a fraction

The probability formula is \(P=\frac{m}{n}\). Substituting the values, we get \(P=\frac{1}{2}\).

Step4: Convert the fraction to a percentage

To convert \(\frac{1}{2}\) to a percentage, we use the formula \(\text{Percentage}=\frac{1}{2}\times100\%\).
