Given :
Number of red marbles = 3
Number of blue marbles = 4
Number of green marbles = 6
Total marbles = 3 + 4 + 6
= 13
Probability = Favorable outcome/Total outcome
Probability of getting red marble = 3/13
Now, remaining marbles = 12
Probability of getting blue marble = 4/12
= 1/ 3
So,
Probability of getting red and blue marble = 3/13 × 1/ 3
= 1/13
