The Union symbol (∪) means “and”, as in event A happening and event B happening. Notice that the sum of all the values in the diagram … Example: considering dice again, if A is “rolls a multiple of 3 ” and B is “rolls 3 or 4 ”, then we have: By looking at where the circles overlap, we notice there is one value, so A\cap B contains one value.

Sets With Notation Venn Diagram Notation & Probability. Looking at the Venn diagram we have here, we can see how many elements are in each set, \(A\), \(B\) and the universal set \(U\). If the probability of one event doesn’t affect the other, you have an independent event. 3. Answer In this chapter we consider discrete, mainly finite, sample spaces An event is any subset of a sample set (including the empty set, and the whole set) Two events that have no outcome in common are called mutually exclusive events. ... As finite probabilities are computed as counts relative to the cardinality of the probability space, the formulas for the principle of inclusion–exclusion remain valid when the cardinalities of the sets are replaced by finite probabilities.
