A bag has 10 green 5 white, and 4 red balls. One ball is drawn at random. What is the probability that it is white?

Answer

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

### Step 1: Identify the total number of balls in the bag.
- The bag contains:
- 10 green balls
- 5 white balls
- 4 red balls

**Total number of balls = Number of green balls + Number of white balls + Number of red balls**
- Total = 10 + 5 + 4 = 19 balls

### Step 2: Identify the number of favorable outcomes.
- The favorable outcome in this case is drawing a white ball.
- From the information given, there are 5 white balls in the bag.

### Step 3: Use the probability formula.
- The probability of an event is given by the formula:

\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \]

- In this case, the probability of drawing a white ball is:

\[ \text{Probability of white ball} = \frac{\text{Number of white balls}}{\text{Total number of balls}} = \frac{5}{19} \]

### Step 4: State the final answer.
- Therefore, the probability of drawing a white ball from the bag is \(\frac{5}{19}\).
