What is AUB example?

The Inclusion Exclusion Principle n(A U B) = n(A) + n(B) – n(A n B) . Example Check that this works for A and B from the example above. A U B = 11,2,3,4,5,6,7,8,9,10l, n(A U B) = 10. A n B = 15,6,7l, n(A n B)

What do square brackets mean in a sentence?

How do you solve AUB?

If A and b are two different events then, P(A U B) = P(A) + P(B) – P(A ∩ B). Consider the Venn diagram. P(A U B) is the probability of the sum of all sample points in A U B.

What are the different types of brackets?
