(a) The transition matrix for this scenario is a 2x2 matrix where the first row represents the probability of transitioning from state 1 ("at work") to either state 1 or state 2 ("absent"), and the second row represents the probability of transitioning from state 2 to either state 1 or state 2.

Given that there is a 78% chance that an employee at work today will be at work tomorrow, the first entry of the first row is 0.78. The second entry of the first row is then 1 - 0.78 = 0.22, representing the probability that an employee at work today will be absent tomorrow.

Similarly, given that there is a 54% chance that an employee absent today will be absent tomorrow, the second entry of the second row is 0.54. The first entry of the second row is then 1 - 0.54 = 0.46, representing the probability that an employee absent today will be at work tomorrow.

So, the transition matrix is [0.78, 0.22; 0.46, 0.54].

(b) To predict the number of employees that will be at work five days from now, we need to raise the transition matrix to the power of 5 and multiply it by the initial state vector, which is [955, 1180 - 955] = [955, 225].

After performing these calculations, the first entry of the resulting vector will give the predicted number of employees at work five days from now.

(c) The steady-state vector is the eigenvector of the transition matrix corresponding to the eigenvalue 1, normalized so that the sum of its entries is 1180. To find it, we need to solve the system of linear equations (T - I)v = 0, where T is the transition matrix, I is the identity matrix, and v is the steady-state vector, and then normalize v.

After solving this system and normalizing the resulting vector, we will get the steady-state vector.
