4 / 12 O 128% A salesperson at the retail outlet has observed a buying pattern over many graduations. All of the last 1000 sales were made by either parents or partners/friends. Of the 400 sales made to partners/friends, 180 were sales of teddy bears and 150 were sales of koalas. Of the 600 sales made to parents, 400 were sales of bunches of flowers. A total of 240 teddy bears were sold. ( see next page) (e) Assuming we can use this information to predict future sales, what is the probability that if a parent makes a graduation gift purchase at this outlet it will be a koala? (3 marks) (f) If a new graduate is given a bunch of flowers from this outlet what is the probability that the flowers were purchased by their partner/ friend
