Could probabilities of two different situations be compared?

Yes, but that might not always make sense.


When two probabilities are added together the probabilty represnts a simple event?

When two probabilities are added together, the result represents the probability of either of the two events occurring, provided that the events are mutually exclusive (i.e., they cannot happen at the same time). If the events are not mutually exclusive, their combined probability would require adjustments to avoid double-counting the overlap. Thus, in the case of mutually exclusive events, the sum of their probabilities is a valid representation of a simple event.


Compare the theoretical probabilities to your experimental probabilities. Why might there be a difference?

Theoretical probabilities are calculated based on ideal conditions and assume that all outcomes are equally likely, while experimental probabilities are derived from actual trials and can be influenced by various factors. Differences between the two can arise due to random variation, sample size, or experimental errors. Additionally, real-world conditions may introduce biases or limitations that deviate from theoretical assumptions. As more trials are conducted, experimental probabilities typically converge toward theoretical probabilities due to the Law of Large Numbers.


When two probabilities are multiplied the probability represents a simple event?

No, it is not.

What is principle of additivity?

The principle of additivity states that the probability of the union of two mutually exclusive events is equal to the sum of their individual probabilities. This means that when events are mutually exclusive (cannot both occur at the same time), their probabilities can be added together to find the probability of either event occurring.
