Question

Theoretical probabilities are Select one: a. the relative frequencies based on an experiment. b. the short-run relative frequencies of an event after infinitely many repetitions. c. the relative frequencies at which an event happens after infinitely many repetitions. d. the long-run relative frequencies based on an experiment.

Answer 1

Answer:

Theoretical probabilities are the long-run relative frequencies based on an experiment.

Step-by-step explanation:

Relative frequency or experimental probability is calculated from the number of times an event happens, divided by the total number of trials in an actual experiment.

With theoretical probability, you don't experiment. Instead, you use what you know about the situation to determine the probability of an event occurring.

Experimental probability approaches theoretical probability when the number of trials is extremely large.

Therefore, theoretical probabilities are the long-run relative frequencies based on an experiment.
