You are given different definitions of a random variable X. Link the definition of the random variable to the appropriate distribution. No work required. X= number of trials until the k-th success occurs. -X= number of successes in n trials. X = -X= number of trials until the 1st success occurs. number of outcomes occurring during a given time interval. X = number of successes in a random sample of size n selected from N items, of which k are labeled success and N-k are labeled as failure.
