@@elliotlingofe7383 no you shouldnt because u already took the person out that won the first prize by writing 9 there so same person cant win the second prize there is no need to divide
@@cwrwn928 isnt it because you can have repeated values? Like P1,P2 wouldnt be the same as P2,P1 in this case because one is winning first place and the other is winning second place, so they are different combinations.
5:26 why do you need to half your answer? the problem is with some of your videos is that sometimes you will tell us to do something but not give the explanation.
Thank U so much❤

It says 2 are selected at random so you have to divide it by 2 get the number of pairs
5:40 why dont u just mulitply the 5 by 2
you can but that only works because you divides the 4 by 2 so if you had 3 x 6 divided by 2 you cant just times by 2. If that makes sense
I still dont understand 😭
Damn
its not hard
it might be a little bit confusing but if u keep doing questions u will get used to it
