Which if the following is a characteristic of a geometric distribution?
Select one:
a. There are more than two possible outcomes.
b. The probability of success is not the same for all trials.
c. There are infinitely many observations.
d. You should perform x trials until you observe a success.
e. Each trial is dependent on the previous trial.

The geometric distribution is the probability distribution of the number of failures we get by repeating trial of experiment until we obtain the first success.

Therefore, option (d) is correct.

d. You should perform x trials until you observe a success

Step-by-step explanation:

In a geometric distribution,there is one or more trials performed will all failures except the first success one.In this theory the number of trials can extend to infinity.There must be at least one.Each trial has the same probability of success or failure.
