Question

1. how is the theoretical probability of an event calculated?

a. \\( \frac { \text { number of trials } } { \text { number of successes } } \\)
b. \\( \frac { \text { number of successes } } { \text { number of non - successes } } \\)
c. \\( \frac { \text { number of favorable outcomes } } { \text { total number of possible outcomes } } \\)
d. \\( \frac { \text { total number of possible outcomes } } { \text { number of favorable outcomes } } \\)

Explanation:

Theoretical probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. Option a is incorrect as it has the ratio reversed (trials and successes). Option b is wrong because non - successes are not part of the theoretical probability formula. Option d also has the ratio reversed.

Answer:

C. \(\frac{\text{number of favorable outcomes}}{\text{total number of possible outcomes}}\)
