 This problem is much harder than the others. Consider a stochastic process $$x(t)$$ that randomly
-switches between x = 0 and x = 1. Let $$\alpha \mathrm{d}t$$ be the probability that it makes a transition from 0 to 1
-during the interval $$\mathrm{d}t$$ if it starts in x = 0, and let $$\beta \mathrm{d}t$$ be the probability that it makes a
-transition from 1 to 0 during $$\mathrm{d}t$$ if it starts in x = 1.

 ### (a)
 
-Write a matrix differential equation for the change in time of the probability $$p_0(t)$$ to be in the 0
-state and the probability $$p_1(t)$$ to be in the 1 state.
