Can somebody me? my teachers are bombarding me with homework this last week and i honestly just need some

I feel ya, at times I don't know what to do I have so much homework, but whihc question do you need help with exactly?
ik:
10. is 1/2 chance- because 4 fake and 4 real= 8 chances and chance of all being real is 4/8 which simplifies to 1/2
12. is 1/8- because there are 16 songs and you listen too 2 so the likely hood of having a favorite and an unfavorite song is 2/16 which simplifies too 1/8
9. is 1/36-because there are 36 different combos such as
123456,134562,145623,156234,162345,213456,234561,245613,256134, and so on and he will only bet one of those combos so it is 1/36
i solved 1/2 of them for you :)

Istg idk..if there all the same length there all the same number but use google
