Enter 3 out of 4 below:
Calculate P(A U B). The formula is denoted below:
P(A U B) = P(A) + P(B) - P(A ∩ B)
P(A U B) = Probability of A Union BP(A U B) = 0.2 + 0.08 - 0.03
P(A) = Probability of A
P(B) = Probability of B
P(A ∩ B) = Proability of what A and B have in common (Intersection)
P(A U B) = 0.28 - 0.03
P(A U B) = 0.25
P(A U B) = 0.25

What 2 formulas are used for the Probability (A U B) Calculator?
What 5 concepts are covered in the Probability (A U B) Calculator?
- intersection
- the set containing all elements of A that also belong to B or equivalently, all elements of B that also belong to A.
A ∩ B - probability
- the likelihood of an event happening. This value is always between 0 and 1.
P(Event Happening) = Number of Ways the Even Can Happen / Total Number of Outcomes - probability (a u b)
- sample space
- the set of all possible outcomes or results of that experiment.
- union
- Combine the elements of two or more sets
