A phenomenon is observed many, many times under identical conditions. The proportion of times a particular event A occurs is recorded. What does this proportion represent?

A) The probability of the event A.

B) The distribution of the event A.

C) The correlation of the event A.

D) The variance of the event A

A. The probability of event A

Step-by-step explanation:

The proportion of times a particular event A occurs is known as the probability of event A because the probability is the measure of uncertainty and by definition probability is calculated as

P (x) = X/n

where

P (x) is the probability of occurring of random variable X

X=number of favorable outcomes

and

n = total number of outcomes.

Thus, the proportion of times a particular event A occurs is known as the probability of event A.
