The contents of three bags, I, II and III are s follows: Bag I:1 white, 2 back and 3 red balls Bag II: 2 white, 1 black and 1 red ball; Bag III: 4 white, 5 black and 3 red balls, A bag is chosen at random and two balls are drawn. what is the probability that the balls are white and red?

Explanation

To solve the problem step by step, we will follow the approach of using the law of total probability.

### Step 1: Define Events
Let:
- \( E_1 \): Event of selecting Bag I
- \( E_2 \): Event of selecting Bag II
- \( E_3 \): Event of selecting Bag III
- \( A \): Event of drawing one white ball and one red ball
