Answer 1

A

Answer 2

It's the same thing over and over; that doesn't happen naturally (hardly ever in life, especially with probability)

Answer 3

Theres more than one answer apparently.

Answer 4

a discrete distribution is valid if all the probabilities sum to one and all the probabilities are non-negative.

Answer 5

A is a valid distribution

Answer 6

it is called a discrete uniform distribution
