A bag contains 7 white balls ,9 green balls and 10 yellow balls . A ball is drawn at random from the bag . What is the probability that it will be
green

Answer

To solve the problem of finding the probability of drawing a green ball from a bag containing different colored balls, we can follow these steps:

### Step 1: Determine the total number of balls in the bag.
- We have:
- 7 white balls
- 9 green balls
- 10 yellow balls

**Total number of balls = Number of white balls + Number of green balls + Number of yellow balls**
\[ \text{Total} = 7 + 9 + 10 = 26 \]

### Step 2: Identify the number of favorable outcomes.
- The favorable outcomes are the number of green balls in the bag, which is 9.

### Step 3: Calculate the probability.
- The probability \( P \) of drawing a green ball is given by the formula:
\[ P(\text{Green}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \]
Substituting the values we have:
\[ P(\text{Green}) = \frac{9}{26} \]

### Final Answer:
The probability of drawing a green ball from the bag is \(\frac{9}{26}\).
