**Q: **Is probability the measure of the likelihood that an event will occur? ¶

**A: **Yes.

**Q: **Is probability Bayesian probability? ¶

**A: **Yes, and which includes expert knowledge as well as experimental data to produce probabilities.

**Q: **Is probability frequentist probability? ¶

**A: **Yes, and which claims that the probability of a random event denotes the relative frequency of occurrence of an experiment's outcome, when repeating the experiment.

**Q: **Is probability a modern development of mathematics? ¶

**A: **Yes.

**Q: **Is probability used to design games of chance so that casinos can make a guaranteed profit? ¶

**A: **Yes, yet provide payouts to players that are frequent enough to encourage continued play.

**Q: **Are probabilities neither assessed independently nor necessarily very rationally? ¶

**A: **Yes.

**Q: **Is probability quantified as a number between 0 and 1? ¶

**A: **Yes, and where, loosely speaking, 0 indicates impossibility and 1 indicates certainty.

**Q: **Is probability the same? ¶

**A: **Yes, and except for technical details.

**Q: **Is probability taken as a primitive and the emphasis is on constructing a consistent assignment of probability values to propositions? ¶

**A: **Yes.

**Q: **Is probability a representation of probabilistic concepts in formal termsâ€”that is? ¶

**A: **Yes, and in terms that can be considered separately from their meaning.

**Q: **Is probability a way of assigning every event a value between zero and one? ¶

**A: **Yes, and with the requirement that the event made up of all possible results is assigned a value of one.
