Raoul's Workout ScheduleDiscrete Mathematics Level 4
Raoul wants to create a weekly schedule for going to the gym. He wants to go to the gym the same three days each week, and he wants there to be at least one day in between each of his visits. How many different ways can Raoul schedule his weekly gym visits?
Details and assumptions
The 'start' date of the week doesn't matter, as this is a weekly event. For example, Raoul does not want to go to the gym on Sunday, Thursday, Saturday, since it means it would be in the gym on Saturday and Sunday of the following week.
