Work Step by Step
a) The number of ways to choose a major and minor is $16P2 = 240$.
b) The number of ways to choose a major, first minor, and second minor is $16P3 = 3360$.
c) The number of ways to choose a major is 16, and the number of ways to choose 2 minors from the remaining subjects is $15P2 = 105$, so in total there are $16 \times 105 = 1680$ ways to choose it.
