Which of the following is an example of theoretical probability?

O A. Lisa attempted 25 basketball free throws and made 14 of them.

The probability Lisa will make a free throw is

14

25

O B. Mike invited 10 friends to a party, and 7 of them said yes. The

probability that a friend will say yes is

7

10

O C. Kelli put 6 red marbles and 5 blue marbles in a bag. The probability

of selecting a red marble is

6

11

O D. Tony listened to 40 songs on the radio and liked 29 of them. The

probability he will like a song is

29

40

The correct answer is C. Kelli put 6 red marbles and 5 blue marbles in a bag. The probability of selecting a red marble is 6 / 11

Explanation:

Theoretical probability occurs as you calculate the probability of a specific outcome in a situation, without experimenting or observing it. Because of this, the probability is theoretical rather than experimental. Also, you can know this, if you divide the number of specific favorable outcomes by the total of possible outcomes.

Option C shows a theoretical probability because this is the only case the probability has not been observed or experimented. Also, expressing the probability as 6/11 is completely correct because 6 is the total of red marbles (possible desired outcomes), while 11 is the total marbles (possible outcomes).
