like for or we use + and for 'and' we use multiplication
I do not add probabilities to anybody!
Empirical probabilities.
Things and numbers don't have probabilities. Situations and events that can happen have probabilities.
If the events are independent then you can multiply the individual probabilities. But if they are not, you have to use conditional probabilities.
Conditional probabilities arise when you revise the probabilities previously attached to some events in order to take new information into account. The revised probabilities are 'conditional on the new information you have received'.

Empirical probabilities.
Sum of all probabilities is 1.
Statistical Probabilities was created on 1997-11-22.
The sum of the probabilities of all possible outcomes is 1.
Things and numbers don't have probabilities. Situations and events that can happen have probabilities.
The fact that probabilities are proportions means that they are less than or equal to 1.
If the events are independent then you can multiply the individual probabilities. But if they are not, you have to use conditional probabilities.
Michel Simonnet has written: 'Measures and probabilities' -- subject(s): Probabilities, Measure theory
Conditional probabilities arise when you revise the probabilities previously attached to some events in order to take new information into account. The revised probabilities are 'conditional on the new information you have received'.
To find the probability of a compound event, you can use the addition rule and the multiplication rule, depending on whether the events are mutually exclusive or independent. For mutually exclusive events, you add their individual probabilities. For independent events, you multiply their probabilities together. If the event involves both types, you may need to combine these rules accordingly. Always ensure to account for any overlaps or dependencies between the events.
