    Three-point distribution

    A poll used a survey of 1008 people to learn how people feel about the economy. Responses were as follows:
    595 people replied 'Economy is growing'
    332 people replied 'Economy is staying about the same'
    81 people replied 'Economy is shrinking'

    Construct a distribution to represent the population such that the survey results above may be seen as a random sample from the population.

    For this question I was given a hint, that I should think about extending a two-point distribution to a three-point distribution.

    Any help would be greatly appreciated
