.
Step-by-step explanation:
Probability : The ratio of favorable outcomes to the total outcomes.
Given that a bag contains 7 marbles which are red in color, 2 marbles which are blue in color and 3 marbles which are green in color.
Total number of marbles = (7+2+3) = 12
The probability of getting a blue on first drawn is



Now the number of blue marbles = (2-1)= 1 [ since 1 blue marbles is drawn]
Total number of marbles = (12-1) =11
The probability of getting a blue marble on second drawn is


Therefore the probability of getting both blue marbles is
