Answer: a) 783 ways; b) 593775 ways
Step-by-step explanation:
a) Your friend wants to select 3 zinfandel out of 9 from the supply in a particular order, which means:



= 783
In the dinner party, the friend will have 783 ways of serving the zinfandel.
b) Now, your friend want to select 6 bottles out of 30 in no particular order and randomly selected. So:



= 593775
If you select 6 bottles randomly from 30, you will have 593775 ways of doing it.
Step-by-step explanation:
a+b=41
let larger number be a and smaller be b
a=21+b
placing value of a in a+b=41
21+b+b=41
2b=41-21
b=20÷2
b=10
so a=21+10
=31
The only way it can be a function is if X is all different
So it has to be B
Monthly, because your value goes up every month.
