** Advertising** Use the following information for Problems 36 and 37. A local business A has two competitors, B and C. No customer patronizes more than one of these businesses at the same time. Initially, the probabilities that a customer patronizes A, B, or C are 0.2,0.6, and 0.2, respectively. Suppose A initiates an advertising campaign to improve its business and finds the following transition matrix to describe the effect.

If A runs the advertising campaign for 3 weeks, find the probability of a customer patronizing each business in the third week.

To determine

**To calculate:** The third probability vector if the transition matrix is

**Given Information:**

The transition matrix is;

And initial probability vector is;

**Formula used:**

The probability vectors depend on the initial probability vector and transition matrix. They are given as;

**Calculation:**

The transition matrix is;

And initial probability vector is;

Use the formula to calculate the first stage probability vector as;
