A jar contains jelly beans. There are 87 pink, 74 purple, 35 white, 70 black, 25 orange, and 47 green. If two jelly beans are chosen from the jar, what is the probability that both are not the same color?
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
