Question

5.22) 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: 
Number of Miles (One-way)
A 	 B	 C	   D	   E	     F
¡Ü5	6-10	11-15   16-20   21-30    ¡Ý31
Relative Frequency   	0.38	0.25	0.16	    0.09      0.07   0.05
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); or C¡¯).
