2. Name the type of the distribution being described (8 Points): A) In the the probability is changing (as with picking daffodil bulbs from a box of daffodil and tulip bulbs) distribution, the random variable X is the number of successes when B) In the the probability is not changing (as with a coin toss). distribution, the random variable X is the number of successes when C) In the toss the coin to finally get a success (either a head or tail, depending on how you define a success). distribution, the random variable Xis the number of times you have to D) In the distribution, the random variable X is the number of times you have to toss the coin to get a fixed number of successes (where the number of successes is two or more).

Explanation / Answer

a) In the Hypergeometric distribution , the random variable X is the number of successes when the probability is changing

b) In the Binomial distribution,  the random variable X is the number of successes when the probability is not changing

c) In Geometric distribution, the random variable X is the number of times you have to toss the coin to finally get a success.

d) In Negative Binomial Distribution, the random variable X is the number of times you have to toss the coin to get a fixed number of success
