In the Brunei, letters can be posted by two services, called ‘first class’ and ‘second class’. First class post is intended to be faster. A letter posted first class on a Monday has the following probabilities of arriving on Tuesday to Friday of the same week. A Wednesday Thursday Friday 0.6 0.2 0.1 0.1 You should assume that the arrival days of letters are independent of one another. I post three letters first class on Monday. Find the probability that They all arrive on Tuesday, None of them arrive on Tuesday, One arrives on Wednesday, one on Thursday and one on Friday.
