1(viii)
A bag contains 3 red and 2 blue marbles. A marble is drawn at random. The probability of drawing a black marble is ∶
- (a)0
- (b)$\frac{1}{5}$
- (c)$\frac{2}{5}$
- (d)$\frac{3}{5}$

Given,
Number of red marbles = 3
Number of blue marbles = 2
The total number of marbles in the bag is 3 + 2 = 5.
Number of black marbles in the bag = 0
Probability = $\frac{\text{No of favorable outcomes}}{\text{Total number of outcomes}}$.
= $\frac{0}{5}$
= 0.
Hence, option 1 is the correct option.
