1. A certain stock price has been observed to follow a pattern. If the stock price goes up one day, there's a 20% chance of it rising tomorrow, a 30% chance of it falling, and a 50% chance of it remaining the same. If the stock price falls one day, there's a 35% chance of it rising tomorrow, a 50% chance of it falling, and a 15% chance of it remaining the same. Finally, if the price is stable on one day, then it has a 50-50 change of rising or falling the next day.

1. A certain stock price has been observed to follow a pattern. If the stock price goes up one day, there's a 20%
chance of it rising tomorrow, a 30% chance of it falling, and a 50% chance of it remaining the same. If the stock
price falls one day, there's a 35% chance of it rising tomorrow, a 50% chance of it falling, and a 15% chance of it
remaining the same. Finally, if the price is stable on one day, then it has a 50-50 change of rising or falling the
next day. Which matrix below is the transition matrix for this Markov chain, if we list states in the order: (rising,
falling, constant).
