In Markov chains, if I was given a transition probability matrix with each of the probabilities specified, then how do I determine the following:1- Probability that state y is visited at least n times given that you start in state x. I know that I can solve it using Px(# of visits to state y ≥ n) = rhoxy(rhoyy)n−1 where rhoxy is the probability that starting at state x, I will be in state y in some positive time (i.e. rhoxy=Px(Ty<[infinity])). But I am not sure how to calculate rhoxy and I have spent so much time trying to figure it out!

Which shows 522 − 482 being evaluated using the difference of perfect squares method?522 − 482 = (2704 + 2304)(2704 − 2304) = 2,003,200

522 − 482 = (52 + 48)(52 − 48) = (100)(4) = 400

522 − 482 = 2704 − 2304 = 400

522 − 482 = (52 − 48)2 = (4)2 = 16

Answers

52² − 48² = (2704 + 2304)(2704 − 2304) = 2,003,200

52² − 48² = (52 + 48)(52 − 48) = 100 * 4 = 400
a² - b² = (a +b)*(a-b)

52² − 48² = 2704 − 2304 = 400

52² − 48² = (52 − 48)² = (4)² = 16

The optionsecond 52² − 48² = (52 + 48)(52 − 48) = (100)(4) = 400 is the correct.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

We know,

a² - b² = (a + b)(a - b)

We have:

= 52² − 48²

After using the above identity, we get:

= (52 + 48)(52 - 48)

= (100)(4)

= 400

Thus, the optionsecond 52² − 48² = (52 + 48)(52 − 48) = (100)(4) = 400 is the correct.

Answers

All given numbers are odd. The sum of odd number (in this case 5) of such numbers is odd too. 30 is an even number, so it's impossible to get 30 in total by adding up any of these numbers.
