here

Step-by-step explanation:

There are total (3 purple + 4 orange + 1 green) = 8 marbles in the bag . Now, 2 marbles out of 8 marbles can be selected in C(8,2) = 8!/2!6! = 28 no. of ways . And 2 purple marbles out of 3 purple marbles can be selected in C(3, 2)

= 3!/2! 1! = 3 no. of ways. Hence the required probability = 3/28

the answer is vanilla
