Solution

A transition matrix for a Markov chain has the property that each row sums to 1, because each row represents a probability distribution over states.

Given the matrix:

x 0.99 0.69 0.32 y 0.14 0.6 0 z

We can calculate the missing values as follows:

  1. For the first row, we have x + 0.99 + 0.69 = 1. Solving for x gives x = 1 - 0.99 - 0.69 = -0.68. However, probabilities cannot be negative, so there seems to be a mistake in the given values.

  2. For the second row, we have 0.32 + y + 0.14 = 1. Solving for y gives y = 1 - 0.32 - 0.14 = 0.54.

  3. For the third row, we have 0.6 + 0 + z = 1. Solving for z gives z = 1 - 0.6 = 0.4.

So, the values of x, y, and z should be x = -0.68, y = 0.54, and z = 0.4, respectively. However, as mentioned, the value for x is not valid in the context of a transition matrix for a Markov chain.

In an office complex of 1180 employees, on any given day some are at work and the rest are absent.
