Given information:
- 2 red, 3 blue, and 5 black balls in a bag
- A ball is drawn from the bag without looking

To find:
- Probability of getting a non-black ball

Solution:
Total number of balls in the bag = 2 (red) + 3 (blue) + 5 (black) = 10

Probability of getting a non-black ball = (number of non-black balls) / (total number of balls)

Number of non-black balls = 2 (red) + 3 (blue) = 5

Therefore, Probability of getting a non-black ball = 5 / 10 = 1/2

Hence, the correct option is (d) 1/2.

Note: It is important to understand that probability is always a ratio of favorable outcomes to total outcomes. In this case, we counted the number of non-black balls as favorable outcomes and the total number of balls as total outcomes to calculate the probability of getting a non-black ball.
