The number of different orders in which Franco can practice the weapon forms can be found using the permutation formula:
n!/(n-r)!
Where n is the total number of items and r is the number of items being chosen at a time. In this case, n = 3 (the number of weapon forms) and r = 3 (he wants to practice all three forms).
So the number of different orders Franco can practice the weapon forms is:
3!/(3-3)! = 3!/0! = 6
Therefore, Franco can practice the weapon forms in 6 different orders.
n!/(n-r)!
Where n is the total number of items and r is the number of items being chosen at a time. In this case, n = 3 (the number of weapon forms) and r = 3 (he wants to practice all three forms).
So the number of different orders Franco can practice the weapon forms is:
3!/(3-3)! = 3!/0! = 6
Therefore, Franco can practice the weapon forms in 6 different orders.
