From past data we know that the mean number of arrivals to buy tickets at the Family Fun Center in Tukwila on Saturday afternoon is 20 per 1/2 hour Assume: The probability of a person arriving is the same for all equal-size intervals Assume: The number of people arriving in any interval is independent of the number of people arriving in any other interval Calculate the probability that 25 people will arrive in 1/2 hour Calculate the probability that between 25 and 30 people (inclusive) will arrive in 1/2 hour Create a discrete probability table with all possible x values and all possible probabilities. For the x values, list 0 to 100. From the table, create a Column Chart that visualizes all possible x values and all possible probabilities.
Note: put all formula inputs in cells, label them, and refer to them in formulas with cell references,
