Web5 be the number of Sylow 5-subgroups of G. Then by the Third Sylow Subgroup Theorem n 5 3 and n 5 ≡ 1 mod 5. The condition n 5 3 implies that n 5 = 1 or n 5 = 3. The case n 5 = 3 is impossible since 3 6≡1 mod 5. Thus n 5 = 1. As above, this implies that if K ≤ G is a Sylow 5-subgroup (that is K = 5) then K /G. We claim that H ∩ K = {1}.
