In how many ways can we choose one number from the set {1,2, 3}, one number from the set {4,5,6}, and one number from the set {7, 8, 9} such that the three could be the sides of a nondegenerate triangle?

2, 6, 7

3, 5, 7

3, 6, 9

So 3 ways. :))

I hope this helped. :)))

I'm sorry, I mistyped 8 for 9.

3, 6, 8 not 3, 6, 9.
