Given :
Number of red marbles = 5
Number of white marbles = 6
Number of blue marbles = 5
Total marbles = 5 + 6 + 5 = 16
Probability = favorable outcome/Total outcome
P(red) = 5/16
P(blue) = 5/15
= 1/3
So, P (red and blue) = 5/16 × 1/3
= 5/48
Thus, probability of drawing red and blue marbles without replacement is 5/48
