Classical probability is when we assume each outcome in a sample space is equally likely, such as with the role of a six -sided number cube, we can actually calculate the probability based on the fact that each side of the number cube has an equal probability of landing face up.

Empirical probability is based on experience.
00:24
We actually perform the experiment, such as possibly rolling that six -sided number cube a thousand times in recording, how many times each number lands face up.

Subjective probability is essentially an educated guess.

If it's the month of july, you might say it's a 60 % chance that the temperature will be above 85 degrees.
00:50
That's just based on experience and what we know about the conditions of the question.

So with a, b, c, and d, what kind of probability are these? probability that a person will watch at 6 o 'clock evening news is 0 .15.
01:09
That's empirical probability.
01:11
Probably based on some kind of survey...
