Answer:
Let n be a whole number, where n! is defined as the product of all whole numbers less than n and including n itself.
The general formula of factorial can be written in fully expanded form as n! =(n-1)!
we know with absolute certainty that 1! =1, where n=1
n! =n×(n-1)!
1! =1×(1-1)!
1! =1×(0)!
1! =1×0!
1! =0!
so yes 0! =1 is correct
