Hello PuP, This post offers so little information as to make it almost meaningless.Traveler visiting 3 museums offering 45 minute tour each. Museum is open 6 hours a day. How many ways can the traveler visit all 3 in one day?
That makes sense, if we suppose that the tours are given during 8 successive fixed time slots, the same at each museum, and it takes no time to get from one museum to any other.How about 8P3?
