Theoretical Probability
Which of the following illustrates theoretical probability?
The probability of drawing a face card from a standard deck of cards is 3/13.
Sally and Tony played rock-paper-scissor 30 times, If Sally lost 14 times,
then probability that Tony won the game is 16/30 = 8/15 = 53.3%.
A spinner with 5 congruent sectors colored yellow, red, blue, green and white is rotated 100 times. If the arrow landed on green 20 times, then the probability of getting a color green is 20/10A spinner with 5 congruent sectors colored yellow, red, blue, green and white is rotated 100 times. If the arrow landed on green 20 times, then the probability of getting a color green is 20/100 = 1/5 = 20%.A spinner with 5 congruent sectors colored yellow, red, blue, green and white is rotated 100 times.

Which of the following is true between the probabilities of the outcomes with 100 trials and 1,000 trials?
The experimental probability of getting a head in 100 trials is lower than the experimental probability of getting a head in 1,000 trials.
The experimental probability of getting a head in 100 trials is higher than the experimental probability of getting a head in 1,000 trials.
There is no difference between experimental probability of getting a head in 100 trials and the experimental probability of getting a head in 1,000 trials.
The experimental probability of getting a head in 100 trials is equal with the experimental probability of getting a head in 1,000 trials.

There is no difference between experimental probability of getting a head in 100 trials and the experimental probability of getting a head in 1,000 trials.
The experimental probability of getting a head in 100 trials is equal with the experimental probability of getting a head in 1,000 trials.
How does an increase in the number of trials in an experiment affect the experimental probability of an event?
The experimental probability tends to get closer to the theoretical probability of the event.
The experimental probability tends to get farther to the theoretical probability of the event.
The experimental probability and the theoretical probability of the event become equal.
The experimental probability does not have definite relationship to the theoretical probability.
