A number of people were asked how many days they would wait to seek medical treatment if they were suffering pain that interfered with their ability to work. The results are presented in the following table.
Number of days: 0 , 1 , 2 , 3 , 4 , 5
Frequency: 27 , 363 , 236 , 107, 19, 10
Consider this collection of people to be a population. Let X be the number of days for a person sampled at random for this population. Find the probability that a person would wait more than 2 days.
Write only a number as your answer. Round to four decimal places (for example: 0.5319). Do not write as a percentage.
