Question

In which of the following should the random variable X not be modeled with a geometric distribution?

Answer 1

Answer:

D)

In a bag of 30 different colored candies, about 20% are red. One candy will be selected one at a time without replacement, and its color will be recorded. Let  X  represent the number of candies selected before red is selected.

Explanation:

The selections are not independent because they do sampling without replacement which makes it so there is not an equal chance of being selected each round.

Answer 2

Answer:

The specification is characterized throughout the explanatory segment below, and according to the particular circumstance.

Explanation:

The 3 geometric distribution generalizations were also:

• For every prosecution, there have been multiple alternative results (successes and failures).
• Trials were indeed autonomous.
• Within each sentencing hearing, the likelihood of success seems to be the same.

Because the probability of substitute isn't constant through each shoot. Therefore, x doesn't ensure that the proposed geometric distribution.
