completely lost..
The thing that screws me most is the fact that it doesn't start from time=0 , but 30 minutes after t=0. =/
Any help is greatly appreciated.
need help with this question... i think i might have the solution, although not quite sure, what i've done is:
1st digit - 2! ways
2nd digit - 10! ways
...
..
..
8th digit - 10! ways
therefore 2! + 7(10!)
is that right?
Need help with question 2 and 3, i can't seem to finish it.
Heres what i've done so far for question 2:
i can only get one case to prove true, the other 2 seem dodgy...
and question 3:
am i going in the right direction?
i'm more concerned about 3 b) though. I can't seem to prove for n=k+1 (I hate factorials)
and this thing is due tomorrow. So need an answer in the next 3 hours.
Any help is appreciated. Thanks!
lol, i've basically screwed up my final school assessment mark pretty badly.
