Question

Before flipping a fair coin, Sunil assesses that he has a 50% chance of obtaining tails. Subjective probability Empirical probability Classical probability b. At the beginning of the semester, John believes he has a 90% chance of receiving straight A’s. Subjective probability Empirical probability Classical probability c. A political reporter announces that there is a 39% chance that the next person to come out of the conference room will be a Republican, since there are 62 Republicans and 95 Democrats in the room. Subjective probability Empirical probability Classical probability

Answer 1

Answer:

a) Classical

b) Subjective

c) Empirical

Step-by-step explanation:

a) Classical probability: In classical probability, all the events have the same probability. When flipping a coin, the probability of getting tails is the same as the probability of getting tails, therefore, the probability of both events is 50%.

b) Subjective probability: Subjective probability is derived from a personal judgement based on previous experiences. In this case, John would be calculating his probability of receiving A's based on his previous semesters.

c) Empirical probability: is the ratio between the number of outcomes a scenario happens and the total of trials in an ACTUAL EXPERIMENT. In this case, the reporter would be calculating this probability based on his previous experiences attending actual conferences.
