Thank you for the opportunity to help you with your question!

Probability of not being same color = 1 - probability of being same color

1 - [ ( # of choosing 2 pink) ( # of choosing 2 purple ) ( # of choosing 2 white ) ( # of choosing 2 black) ( # of choosing 2 orange) ( # of choosing 2 gree) / # of choosing 2 

= 1 - [ 3741+2701+595+2415+300+1081]/56953 =1 - .19 = 0.8098

Please let me know if you need any clarification. I'm always happy to answer your questions.
