you spin the spinner once. what is p(even)? write your answer as a fraction or whole number.

Explanation:

Step1: Count total outcomes

There are 4 sections on the spinner, so total outcomes = 4.

Step2: Count favorable outcomes

Even - numbered sections are 2 and 4, so favorable outcomes = 2.

Step3: Calculate probability

Probability formula is $P(A)=\frac{\text{Favorable Outcomes}}{\text{Total Outcomes}}$, so $P(\text{even})=\frac{2}{4}=\frac{1}{2}$.

Answer:

$\frac{1}{2}$
