you spin the spinner once. what is p(4 or even)? write your answer as a fraction or whole number.

Explanation:

Step1: Identify total outcomes

The spinner has 3 sections, so the total number of possible outcomes is 3.

Step2: Identify favorable outcomes

The numbers on the spinner are 2, 3, 4. The event of getting a 4 or an even - number includes 2 and 4. So there are 2 favorable outcomes.

Step3: Calculate probability

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(4\text{ or even})=\frac{2}{3}$.

Answer:

$\frac{2}{3}$
