Answer:
a) 5
b) 10
c) 70
d) 1
e) 1
f) 924
Explanation:
a) C(5,1)
By combination method nCr = n!/(n-r)!r!
= 5C1 = 5!/(5-1)!1!
= 5
b) C(5,3)
5C3 = 5!/(5-3)!3!
= 10
c) C(8, 4)
8C4 = 8!/(8-4)!4!
= 70
d) C(8, 8)
= 8C8 = 8!/(8-8)!8!
= 1
e) C(8, 0)
8C0 = 8!/(8-0)!0!
= 1
f ) C(12, 6)
= 12C6 = 12!/(12-6)!6!
= 924
