Hi, I am currently learning Grade 12 Data Management online and I have come across a few questions that I am stuck on.

They are:

Solve fornwhere:

a)n!divided by (n- 2)! = 930 (4 marks)

b) P(n,5) = 42 x P (n,3) (5 marks)

21. a) From the wordparallel ...

a) How many arrangements can be formed from all the letters in the wordparallel?

My answer:

8! divided by 3! 2! = 3360 (because there are 8 letters total, divided by 3 of the same letter 'L' and 2 of the same letter 'A')

b) In how many of these arrangements will the 3 "l's" be together?

If someone could help me that would be greatly appreciated!!
