A bag contains a red ball, a blue ball and a yellow ball, all the balls being of the same size. If a ball is drawn from the bag, without looking into it, find the probability that the ball drawn is:
blue

Answer

To find the probability of drawing a blue ball from the bag, we can follow these steps:

**Step 1: Identify the total number of balls in the bag.**
- The bag contains one red ball, one blue ball, and one yellow ball.
- Therefore, the total number of balls = 3.

**Step 2: Identify the number of favorable outcomes for drawing a blue ball.**
- There is 1 blue ball in the bag.

**Step 3: Use the formula for probability.**
- The probability (P) of an event is given by the formula:
\[ P(\text{event}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \]
- In this case, the event is drawing a blue ball.

**Step 4: Substitute the values into the formula.**
- Number of favorable outcomes (blue balls) = 1
- Total number of outcomes (total balls) = 3
- Therefore, the probability of drawing a blue ball is:
\[ P(\text{blue ball}) = \frac{1}{3} \]

**Final Answer:**
The probability that the ball drawn is blue is \(\frac{1}{3}\).
