In 2016, Red Rose tea randomly began placing one of ten English porcelain miniature figurines in a l00 bag box of the tea, selecting from ten figurines in the American Heritage Series. (a) On the average, how many boxes of tea must be purchased by a customer to obtain a complete collection consisting of the ten different figurines? (b) If the customer uses one tea bag per day, how long can a customer expect to take? on the average, to obtain a complete collection?
For this question, I don't even know where to start. Can someone please give me hint?
