Q. At the school carnival, Nicole is in charge of a spinner game where students can win prizes. The spinner is divided into 44 unequal sections labeled book, sticker, eraser, and keychain. Nicole keeps track of what prizes the spinner lands on for the first 88 students who play. Here are her results:\newlinesticker, book, eraser, keychain, sticker, eraser, sticker, keychain\newlineBased on the data, what is the probability of the spinner landing on keychain?\newlineWrite your answer as a fraction or whole number.\newline
  1. Count keychain spins: Count the number of times the spinner landed on keychain.\newlineCalculation: 22 times.
  2. Total spins count: Count the total number of spins.\newlineCalculation: 88 spins.
  3. Calculate keychain probability: Calculate the probability of landing on keychain.\newlineCalculation: Probability = Number of keychain outcomes / Total number of spins = 28\frac{2}{8}.
  4. Simplify fraction: Simplify the fraction.\newlineCalculation: 28\frac{2}{8} simplifies to 14\frac{1}{4}.
