I'm not so sure about the others but for 1 I'm pretty sure it's 60.
Basically what you can do is multiply the number of shoes by the number of pants and then multiply that product by the number of shirts.
3 × 4 = 12
Multiply 12 by the number of shirts
12 × 5 = 60
Kyle can make 60 outfits with one pair of shoes, one pair of pants, and a shirt.
Edit: Alright I figured out 3
So the outcomes where there is at least 1 five are the following
(1,5),(2,5),(3,5),(4,5),(5,5),(6,5)
(5,5),(5,4),(5,3),(5,2),(5,1)
So the probability of at least one five in two number cube rolls is 11/36. As a percentage that's 30.55555556 and as a decimal it's 0.30555...
