One environmental group did a study of recycling habits in a California community. It found that 71% of the aluminum cans sold in the area were recycled. (Round your answers to four decimal places.)
(a) If 393 cans are sold today, what is the probability that 300 or more will be recycled?
(b) Of the 393 cans sold, what is the probability that between 260 and 300 will be recycled?
