Four people select a main dish from a menu of 7 items. How many choices are possible:
a) If a record is kept of who selected which choice (as a waiter would)
b) If who selected which choice is ignored (as a chef would). Analyze this part by the number of different choices made.
This solution shows how to compute the number of combinations for part (a) and the number of permutations for part (b). The solution is provided within a Word document which is attached and includes all calculations.
