hi there need help :

a) How many outcomes are there if four distinct dice are rolled? (So, for example, 2, 3, 5 and 6 on the 1

st, 2nd, 3rd and 4th die and 6, 5, 3 and 2 on the 1st, 2nd, 3rd and 4th die are considered as different.)

b. How many outcomes are there if four indistinguishable dice are rolled? (So, for example, the outcomes 2, 3, 5, 6 and 6, 5, 3, 2 are considered the same.)

c. How many outcomes are there where four distinct dice are rolled and each shows a different number?

d. How many outcomes are there where four indistinguishable dice are rolled and

each shows a different number?
