1.)Find the values of random variables. a.)When a faculty member at a university is invited to the reception of commencement exercises, he or she may choose not to attend, to attend alone, or to attend with a guest. The random variable x is the number of event attendees for a faculty member. b.)A green die and a red die are rolled. The random variable X is the number of rolls required until a sum of seven spots is attained for the first time. c.)Four students are applying for a summer job in a fast-food restaurant. The result of the application is that a student may be hired or rejected. Assume that a student is equally likely to be hired or rejected for the job.
