This probability distribution represents the likelihood of a certain number of people sitting at the specific table in a day. The random variable X is the number of people in a party, and its possible values are 1, 2, 3, 4, 6, or 0.
The relative frequency column represents the proportion of days in the week where a certain number of people sat at the table. For example, there is a 0.46 probability that a party of 2 people will sit at the table on any given day of the week.
Note that the sum of all the probabilities must equal 1, since there must always be some number of people sitting at the table.
A restaurant manager tracks the number of people in every party to sit at a specific table every day for a week, and then compiles the results into a probability distribution as shown in the table: Number of People , X 12346 Relative Frequency P(X) 0.05 0.46 0.18 0.22 0.06 0.03
