Answer 1

Answer:

The cumulative distribution function (c.d.f.) of a discrete random variable X is the function F(t) which tells you the probability that X is less than or equal to t. ... In other words, for each value that X can be which is less than or equal to t, work out the probability that X is that value and add up all such results.
