Going to bed early has been shown to have a positive impact on my happiness level. When I go to bed early the next day, I am a 9 out of 10 for a happiness level. If I go to bed at a normal time, the next day my happiness level is a 6 out of 10. If I go to bed late, the following day I have a happiness level of 1 out of 10. Historically, in a given week, I go to bed early once, on time four times, and late twice. Based on this, what is my expected happiness level for tomorrow? Justify your answer
