It is the likeliness of an event happening based on all the possible outcomes. The ratio for the probability of an event 'P' occurring is P (event) = number of favorable outcomes divided by number of possible outcomes.
From the letters A, E, I, O, U the theoretical probability of selecting the letter E is 1/5
A. 0.5
B. 0.25
C. 0.42
D. 0.6
Correct answer: A
Step 1: Theoretical probability = number of favorable outcomes / number of possible outcomes.
Step 2: The probability of the coin lands on the black square is 32.
Step 3: Total number of outcomes = 64.
Step 4: P (event) = 32/64
Step 5: = 1/2 = 0.5
Step 6: The theoretical probability that the coin lands on a black square is 0.5.
Q1: What is the theoretical probability of rolling a 4 on a standard six-sided die?
Q2: A bag contains 3 red marbles and 5 blue marbles. What is the theoretical probability of picking a red marble?
Q: What is the difference between theoretical and experimental probability?
A: Theoretical probability is what we expect to happen, while experimental probability is what actually happens after conducting an experiment.
Q: Can theoretical probability be greater than 1?
A: No, theoretical probability always lies between 0 and 1, inclusive.
