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

Explanation:

Step1: Identify total outcomes

The spinner has 4 sections, so the total number of possible outcomes is 4.

Step2: Identify favorable outcomes

The numbers on the spinner are 1, 2, 3, 4. The event "4 or even" includes the numbers 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 $P(4\text{ or even})=\frac{2}{4} = 0.5$.

Step4: Convert to percentage

To convert a decimal to a percentage, multiply by 100. So $0.5\times100 = 50%$.

Answer:

50%
