Question

To define a discrete probability distribution f, the necessary conditions that need to hold for each possible outcome, x, are:

f(x) ≥ 0, i.e. the probability has to be non-negative

The sum of f(x) over all possible values of x should add up to 1.

P(X = x) = f(x), i.e. f(x) denotes the probability that the random variable for the possible outcomes is equal to x.

All of the above Only (a) and (b)

Answer 1

Ans : All of the above
