Negar wants to randomly select 15 students of all her former BUS232 students who got A , and make a team to work on a research hypothesis. So far, she has taught BUS232 five times with total of 800 students, of which 30 got A . In her team she wants to have 5 managers and coordinators and the rest will be regular team members (10). So, when she starts to randomly select students, the first selected student will be the Principal manager, the second will be the general manager, the third will be the Data sampling manager, the fourth will be the assistant manager, and the fifth will be the coordinator. Then the next 10 will be regular team members. How many different combinations her team can have? (For the first 5: ordering matters and for the remaining 10: ordering does not matter)
