Answer – (C)
Solution:
This second part of the problem is similar to the first except that the choice of the second group of 3 comes only from the sophomores.
Again we want 3 freshmen and 3 sophomores so we multiply the number of groups of freshmen times the number of groups of sophomores.
C35*C38= 560
