The number of sequences of 4 fish that can be moved from the tank can be calculated using combinations. We need to choose 4 fish out of 5, without regard to order. This can be represented mathematically as:
5 choose 4 = 5C4 = 5!/((5-4)!4!) = 5
Therefore, there are only 5 possible sequences of 4 fish that can be moved from the tank.
Warren has 5 different fish in a small, crowded tank. He decides to randomly scoop up individual fish and transfer them to a new tank until a total of 4 fish have been moved. How many sequences of 4 fish are possible?
