There are three urns A, B and C. Urn A contains 4 white balls and 5 blue balls. Urn B contains 4 white balls and 3 blue balls. Urn C contains 2 white balls and 4 balls. One ball is drawn from each of these urns. What is the probability that out of these three balls drawn, two are white balls and one is a blue ball?

Explanation

To solve the problem of finding the probability that out of the three balls drawn from urns A, B, and C, two are white and one is blue, we can break it down into systematic steps.

### Step 1: Identify the contents of each urn
- **Urn A**: 4 white balls and 5 blue balls
- **Urn B**: 4 white balls and 3 blue balls
- **Urn C**: 2 white balls and 4 blue balls

### Step 2: Determine the total number of balls in each urn
