Assume that P ( A ) = P ( B ). Show that A = B
Solution:
Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
For an experiment having n number of outcomes, the number of favorable outcomes can be denoted by x.
Let P (A) = P (B)
Let x ∈ A
A ∈ P (A) = P (B)
Therefore,
x ∈ C, for some C ∈ P (B)
Now, C ⊂ B
Hence, x ∈ B
So, A ⊂ B
Similarly, B ⊂ A
Therefore, A = B proved
