The histogram below gives the length of service of members of the Department of English at a particular university. The classes, in years of service, are 0−−4.9, 5−−9.9, etc., and the vertical axis represents the number of faculty. 1) What percent of the department faculty have less than 15 years of service? 2) If a member of the department is chosen at random to serve on a university committee, what is the probability (in decimal form) that the chosen representitive will have between 5 and 45 years of service? 3) What is the probability the representative above will have less than 20 years of service given that the person has less than 25 years of service?
