Which statement correctly describes the cumulative distribution function (CDF) of a random variable X?

Show Answers

It accumulates probabilities starting from higher values of x.It accumulates probabilities beginning from the smallest value up to a given value of x.It accumulates probabilities from zero to a particular value of x.None of the above.

Explanation

The CDF of a random variable X represents the probability that X takes a value less than or equal to a specific point. This means it accumulates probabilities starting from the smallest possible value up to that point. Therefore, option B is correct.
