Over a 30 day (one month) period, Doug charts how often he is happy and sad.

If Doug is happy one day, the probability he will be happy the next day is 0.7, and the probability he would be sad the next day is 0.4. Day 0, aka the day before the first day of the month, he is happy. Run a simulation in R to find the probability of Doug having more sad days than happy days over the course of the 30 day period.
