To answer the question, we need to know the distribution of the colors and numbers on the spinner. However, since this information is absent, I'll explain the general method for determining the probability.
If we assume that the spinner has a set of numbers that are either even or odd, along with colors such as blue, red, etc., we can calculate the probability as follows:
- Identify the total number of even numbers that are blue.
- Identify the total number of blue sections on the spinner.
- Use the formula for conditional probability:
\[ P(\text{Even} | \text{Blue}) = \frac{P(\text{Even and Blue})}{P(\text{Blue})} \]
This tells us the probability of landing on an even number given that the spinner has landed on blue.
Without specific numbers of even numbers and their color combinations, it's impossible to compute the exact probability.
If any of the given responses (50%, 67%, 25%, 38%) are based on context not provided, please share the details about the spinner so we can determine which response is correct.
