Probability help.....plezz

hi just started stats at uni and having a little trouble getting sum questions like the one below any help would be great thanks.(Cool)

Records show that 35% of the students successfully completing STAT111 also do MATH108 as part of their degree.

A group of 10 students is selected at random. Find the probability that:

(1) None of a randomly selected group of 10 students successfully completing STAT111 also do MATH108 as part of their degree.

(2) Less than half of the group of 10 students successfully completing STAT111 also do MATH108 as part of their degree.
