Answer: Option (Login/Signup)

Show Explanation

Answer: 10/21

Solution: 2 red, 3 green, and 2 blue balls are there. So the probability of getting no blue ball is not selecting any blue ball among the two chosen balls hence 5C2.

5C2/7C2 = 10/21.

7C2 because we can select any 2 balls from 7 balls in that number of ways.
