Q. A wilderness retail store asked a consulting company to do an analysis of their hiking shoe customers. The consulting company gathered data from each customer who purchased hiking shoes, and recorded the shoe brand and the customer's level of happiness.\begin{tabular}{|l|c|c|}\hline & A Footlong shoe & A Toes Knows shoe \\\hline Displeased & 3 & 3 \\\hline Pleased & 3 & 3 \\\hline\end{tabular}What is the probability that a randomly selected customer is pleased or purchased a Toes Knows shoe?Simplify any fractions.□
Customers who purchased Toes Knows: Customers who purchased Toes Knows =Displeased Toes Knows+Pleased Toes KnowsCustomers who purchased Toes Knows =3+3Customers who purchased Toes Knows =6
Probability of pleased customer: Probability of pleased customer = Total customersPleased customersProbability of pleased customer = 126Probability of pleased customer = 21
Probability of purchasing Toes Knows: Probability of purchasing Toes Knows = Customers who purchased Toes Knows 126Probability of purchasing Toes Knows = 21
Probability of pleased or Toes Knows: Probability of pleased or Toes Knows = Probability of pleased customer + Probability of purchasing Toes Knows − Probability of pleased and Toes KnowsProbability of pleased or Toes Knows = 21 + 21− (Pleased Toes Knows / Total customers)Probability of pleased or Toes Knows = 21 + 21− (123)Probability of pleased or Toes Knows = 21 + 21−212Probability of pleased or Toes Knows = 213−212Probability of pleased or Toes Knows = 216
