Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

The sample space is S={0, 1, 2, 3, 4}. Suppose that
Pr({0}) = 0.2
Pr({1}) = 0.3
Pr({2}) = 0.4
Pr({3}) = 0.1
Pr({4}) = 0.0.
Find Pr(A)and Pr(Ac) if A={0, 1, 2}and Pr(B) if B={0, 2, 4}. Is Pr(A∪B) = Pr(A)+ Pr(B)?Why or why not?

Definition Definition For any random event or experiment, the set that is formed with all the possible outcomes is called a sample space. When any random event takes place that has multiple outcomes, the possible outcomes are grouped together in a set. The sample space can be anything, from a set of vectors to real numbers.
