Based on the information in given Exercise, if a person is known to travel a one-way distance of at least 11 miles to work, determine the probability that he or she drives at least 31 miles to work.
Exercise
A survey of employees at a large company found the following relative frequencies for the one-way distances they had to travel to arrive at work:
a. What is the probability that a randomly selected individual will have to travel 11 or more miles to work?
b. What is the probability that a randomly selected individual will have to travel between 6 and 15 miles to work?
c. Draw a Venn diagram that includes the relative frequency probabilities in the table.
d. Using the letter identifications provided, calculate the following probabilities: P(A or B or E); P(A or F); P(A' or B); P(A or B or C').
