Option C
<u>ANSWER: </u>
The probability of choosing 2 green balls and 1 red ball is 
<u>SOLUTION:
</u>
Given, there are 2 red and 5 green balls in a bag.
So, there are 7 balls in the bag.
We need to find the probability of choosing 2 green balls and 1 red ball.
Probability of 2 green balls and 1 red ball = probability of 1st green ball
probability of 2nd green ball x probability of 1 red ball.
Now, probability of 1st green ball = 
= 
because we are replacing after every pick.
Now, probability of red ball = 

Probability of 2 green balls and 1 red ball = 


Hence, the probability of choosing 2 green balls and 1 red ball is
