a. Three different letters are to be mailed to 3 persons. If the three letters are to be put at random into three envelopes addressed to the persons, list the six possible ways in which this can be done. If X represents the number of letters in their correct envelopes, deduce the probability distribution of X.
b. A random variable X can assume only the values 2 and 5. If it’s mean is 4, find the probability of these points.
