Answer:
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
Answer:
1/15
Step-by-step explanation:
3 red, 1 blue, 2 purple
P of purple and blue is the
