  1. Count Keychain Spins: Count the number of times the spinner landed on keychain.\newlineKeychain count: 22
  2. Total Spins Count: Count the total number of spins.\newlineTotal spins: 88
  3. Calculate Probability: Calculate the probability of landing on keychain.\newlineProbability = Number of keychain outcomesTotal number of spins\frac{\text{Number of keychain outcomes}}{\text{Total number of spins}}\newlineProbability = 28\frac{2}{8}
  4. Simplify Fraction: Simplify the fraction. 28\frac{2}{8} simplifies to 14.\frac{1}{4}.
