The following table lists thefrequency distribution of the data collected by this agency.5.Number of TV sets owned1234Number of families120970730410270(a)Construct a probability distribution table for the numbers of television setsowned by these families. Draw a bar graph of the probability distribution.Are the probabilities listed in the table of part a) exact or approximateprobabilities of various outcomes? Explain.Let X denote the number of television sets owned by a randomly selectedfamily from this town. Find the following probabilities.(i)(iii)Find the mean and standard deviation for the probability distributiondeveloped for the number of television sets owned by all 2500 families in atown.
