use the venn diagram in Part A to find each probability when annie randomly chooses one member of the doubles club. (need help w

Usimov [2.4K]

If we assume the club membership includes

$\bullet\ \mbox{6 junior boys}\\ \bullet\ \mbox{8 junior girls}\\ \bullet\ \mbox{16 senior boys}\\ \bullet\ \mbox{12 senior girls}$

then the blanks in the Juniors circle must be filled in with 6 and 8 (with the 8 going in the overlap with girls). The remaining blank in the Girls circle must be filled in with 12, the number of senior girls. The blank outside both circles is the number of senior boys (members who are not juniors and not girls), 16.
