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 blue ball?
Solution:
To find the probability of drawing a blue ball, we need to determine the number of favorable outcomes (blue balls) and the total number of possible outcomes (all balls in the bag).
Favorable Outcomes:
There are 3 blue 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.
Probability:
The probability of an event can be calculated by dividing the number of favorable outcomes by the total number of outcomes.
Probability of drawing a blue ball = Number of blue balls / Total number of balls
Probability of drawing a blue ball = 3 / 10
Simplifying the fraction, we get:
Probability of drawing a blue ball = 3/10
Therefore, the probability of getting a blue ball is 3/10 or option 'c'.

Total Outcomes:
There are a total of 2 red balls + 3 blue balls + 5 black balls = 10 balls in the bag.
Probability:
The probability of an event can be calculated by dividing the number of favorable outcomes by the total number of outcomes.
Probability of drawing a blue ball = Number of blue balls / Total number of balls
Probability of drawing a blue ball = 3 / 10
Simplifying the fraction, we get:
Probability of drawing a blue ball = 3/10
Therefore, the probability of getting a blue ball is 3/10 or option 'c'.
