A letter posted second-class on a Monday has the following probabilities of arriving on Tuesday to Friday of the same week. A Wednesday Thursday Friday 0.1 0.2 0.3 0.4 Again, you should assume that the arrival days of letters are independent of one another. I post one letter first class and one letter second-class on Monday. Find the probability that  The two letters arrive on the same day,  The second-class letter arrives before the first class letter.
