(a) 5 trucks should carry 50 boxes, but only 2 trucks are available. In how many different ways boxes can be chosen to fit in 2 trucks:

- Order of boxes is important

- Order of boxes is irrelevant

(b) How many different arrangements are there of the letters of the word FLOWER which end in a vowel?

----------------------------------------------

My attempt for (a)

50/5 = 10, so each truck can carry 10 boxes

Order Important: 50P20

Order Irrelevant: 50C20

---------------------------------------------

My attempt for (b)

there are 6 letters

_ _ _ _ _ _

there are 2 vowels and they must appear at the end (they can appear in two different ways)

_ _ _ _ _ 2

there are 4 constants and they have no restrictions

5 x 4 x 3 x 2 x 1 x 2
