Answer:
There are 504 difference outdoor expeditions possible.
Explanation:
We can solve problems like this using multiplication rules. Since the order of events in the expedition does not matter, we can multiply all numerical values in any order we so choose. In this case, our numerical values are four hunting, seven fishing, six hiking, and three camping events.
4 x 7 x 6 x 3 = 504
There are 504 difference outdoor expeditions possible.
