Answer:The formula for a combination of choosing r unique ways from n possibilities is:
nCr = n!
r!(n - r)!
where n is the number of items and r is the unique arrangements.
Plugging in our numbers of n = 10 and r = 0, we get
10C0 = 10!
0!(10 - 0)!
10C0 = 3,628,800
3,628,800
In the first part, there are 10 fish total. 6/10 = 3/5 which means that there were 3/5 goldfish. When she buys two more, the total becomes 12 and 4/12 = 1/3 Hope this helps!
