# p a and b complement ?

What is the complement of a and B?

A Intersection B Complement is equal to the union of the complements of the sets A and B. Mathematically, it is written as (A ∩ B)' = A' U B'. It is one of the important De-Morgan's Law of sets.

Is it easier to calculate P (a') first or the complement?

But the complement (which is when the two scores are the same) is only 6 outcomes: So in this case (and many others) it is easier to work out P (A') first, then calculate P (A) = 1 − P (A')

How do you find the P (A^C) of complementary events?

P (A^c) = 1- P (A) P (Ac) = 1−P (A). Note: this does not, however, mean that any two events whose probabilities total to 1 are each other's complements; complementary events must also fulfil the condition of mutual exclusivity.

What is the complement of probability?

Probability of an event happening = Number of ways it can happen Total number of outcomes The complement is shown by a little mark after the letter such as A' (or sometimes Ac or A ): It makes sense, right? Event A plus all outcomes that are not Event A make up all possible outcomes. Why is the Complement Useful?

### 8. What is probability of a intersection B complement?

14 hours ago Let's call the universe of all possible outcomes, U. Then, the complement of B is defined as all of U that are not in B, i.e. U - B. So then we can prove your assertion like this: [math]P(A\cap B^c)=P(A\cap (U-B))=P(A\cap U)-P(A\cap B)=P(A)-P(A\cap B)[/math]. And that's what you re looking for.
