A company experiments with thnee website designs to see which one would lead to the highest probability of purchase. The rst (design A) used enhanced product information, the second (design B) used extensive iconography, and the third (design 0) allowed the customer to submit their own product ratings. Aer 6 weeks of testing, the designs delivered probabilities of purchase of 6%, 4%, and 3% respectively. Equal numbers of customers were sent randomly to each website design. Complete parts a through d below. a) Constmct a probability tree for this experiment. Purchase . Design A Desrgn Aand Purchase W Design Aand No Purchase Purchase . Design B Desrgn B and Purchase W Design B and No Purchase Purchase . Design C Desrgn C and Purchase W Design 0 and No Purchase (Round to three decimal places as needed.) b) What percent of customers who visited the site made a purchase? % (Round to one decimal place as needed.) c) What is the probability that a randomly selected customer was sent to design C? (Round to three decimal places as needed.) (1) Given that a customer made a purchase, what is the probability that the customer had been sent to design C? (Round to three decimal places as needed.)
