To solve the probability questions about the spinner, we need to know what numbers are present on the spinner. However, since the details of the spinner (the numbers it contains) are not provided, I will give you a general method for calculating the probabilities based on any hypothetical spinner.

  1. Probability of landing on an even number:

    • Count the total number of sections on the spinner (let's call this total \( N \)).
    • Count how many of those sections have an even number (let's call this count \( E \)).
    • The probability \( P \) of landing on an even number is calculated as: \[ P(\text{even}) = \frac{E}{N} \]
  2. Probability of landing on a number greater than 20:

    • Count how many of those sections have a number greater than 20 (let's call this count \( G \)).
    • The probability \( P \) of landing on a number greater than 20 is calculated as: \[ P(\text{greater than 20}) = \frac{G}{N} \]

Without specific numbers on the spinner, you will need to identify \( N \), \( E \), and \( G \) based on the actual content of the spinner. Once you have those counts, you can plug them into the formulas above to get the decimal probabilities.
