Answer:

C(2,r)

C(6, r)

20 ways

Step-by-step explanation:

(a )Selection can be dependent on whether there is order or not. Assume there is no order of selection, the function is given by

Selection =C(n, r) ......(1)

Selection = C(2,r)

Where C is a combination function, n is the number of oranges and is the number of oranges selected at a time.

Assuming 1 at a time

Selection = 2C1 = 2! = 2 ways

(f)For the combination of oranges, banana and apples. We assume the apples and banana are identitcal to each other as the the oranges and are of the same number

n = 6, n(O) = 2, n(B) = 2, n(A)= 2

Selection = C(n,r)

= C(6,r)

(g) Selection = C(6, 3)

Selection = 6C3 = [6 × 5 × 4× 3!]/3!3!

= (6×5×4)/3×2

= 20ways
