Question

for any probability density function, what value is always the total area under the curve? choose the correct answer below. a. 0 b. 2 c. 1 d. it depends on the specific probability density function.

Explanation:

By the definition of a probability density function, the total area under its curve over its entire domain represents the total probability of all possible events. Since the sum of probabilities of all possible outcomes in a sample - space is 1, the total area under the curve of any probability density function is 1.

Answer:

C. 1
