Question

for an event A,find P(A) + P(not A)​

Answer 1

Answer:

Step-by-step explanation:

Probability P is a real-valued function defined on events of a sample space S ... Law of the complement: P(not A) = 1 - P(A) . ... Given: P(A ) = 0.5 , P(B) = 0.4 , and P(A and B ...

Answer 2

For an event P(A) + P(not A) is equal to the Universal set.

• A universe set (usually defined as a U) is a set that has the characteristics of all related sets, without duplication. It states that if A and B are two sets, such as A = {1,2,3} and B = {1, a, b, c}, then the universe set associated with these two sets is given by U = {1, 2,3, a, b, c}.
• In Mathematics, a set of objects or a set of objects is called a Set. There are different types of sets like Empty Set, Complete Set, Endless Set, Equal Set, Subset Set, Superset and International set. All of these sets have their own Mathematical significance.
• There are many uses for sets in our daily lives, but they are often used to represent bulk data or data collection on a website. For example, our hand is a set of fingers, where each finger is unique. Set writing is usually given in parentheses, {} and each part of the set is separated by commas such as {4, 7, 9}, where 4, 7, and 9 are set items.
