Question

you flip a coin. what is p(heads)? $\frac{1}{2}$ 1 $\frac{1}{4}$ $\frac{1}{5}$

Explanation:

Step1: Identify total outcomes

A coin - flip has 2 possible outcomes (heads or tails).

Step2: Identify favorable outcomes

The favorable outcome (getting heads) is 1.

Step3: Calculate probability

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

Answer:

A. $\frac{1}{2}$
