The resumes of two male applicants for a college teaching position in chemistry

Question

The resumes of two male applicants for a college teaching position in chemistry are placed in the same file as the resumes of two female applicants. Two positions become available, and the first, at the rank of assistant professor, is filled by selecting one of the four applicants at random. The second position, at the rank of instructor, is then filled by selecting at random one of the remaining three applicants. Using the notation M_2F_1, for example, to denote the simple event that the first position is filled by the second male applicant and the second position is then filled by the first female applicant, (a) list the elements of a sample space S: (b) list the elements of S corresponding to event A that resumes of two male applicants for a college the position of assistant professor is filled by a male applicant: (c) list the elements of S corresponding to event B that exactly one of the two positions is filled by a male applicant: (d) list the elements of S corresponding to event C that neither position is filled by a male applicant: (e) list the elements of S corresponding to the event A intersection B: (f) list the elements of S corresponding to the event A union B: (g) construct a Venn diagram to illustrate the intersections and unions of the events A, B, and C.

(b) A = { M1F1 , M1M2 , M1F2 , M2F1 , M2F2 , M2M1 }

(c) B = { M1F1 , M1F2 , M2F1 , M2F2 , F1M1 , F1M2 , F2M1, F2M2 }

(d) C = { F1F2 , F2F1 }
