Purple flowers (P) are dominant over white flowers (p). Round seeds (R) are dominant over wrinkled seeds (r). Green seeds (G) are dominant over yellow seeds (g). You cross a plant that is heterozygous for Purple flowers, heterozygous for Round seeds and homozygous for yellow seeds with a plant that is homozygous for white flowers, heterozygous for Round seeds and heterozygous for Green seeds.  What is the probability the offspring from this cross will express at least 2 dominant traits?  Express your answer as a reduced fraction.
