Problem: There are 2 Red, 3 Blue, and 5 Black balls in a bag. A ball is drawn from the bag without looking into the bag. What is the probability of getting a red ball?
Solution:
To find the probability of getting a red ball, we need to determine the number of favorable outcomes (red balls) and the total number of possible outcomes (total balls).
Favorable outcomes:
There are 2 red balls in the bag.
Total outcomes:
There are a total of 2 red balls + 3 blue balls + 5 black balls = 10 balls in the bag.
Therefore, the probability of getting a red ball can be calculated as:
Probability = (Number of favorable outcomes) / (Total number of outcomes)
= 2 / 10
= 1 / 5
Therefore, the probability of getting a red ball is 1/5 or option 'C' in the given options.

Therefore, the probability of getting a red ball can be calculated as:
Probability = (Number of favorable outcomes) / (Total number of outcomes)
= 2 / 10
= 1 / 5
Therefore, the probability of getting a red ball is 1/5 or option 'C' in the given options.
