What is E and F in probability class 12?
Multiplication Rule Let E and F be two events associated with a sample space S. Clearly, the set E ∩ F denotes the event that both E and F have occurred. In other words, E ∩ F denotes the simultaneous occurrence of the events E and F. The event E ∩ F is also written as EF.
How do you find the probability of a class 12?
The important Probability Formulas Class 12 are: The conditional probability of an event E, given the occurrence of the event F is given by P(E | F) = P(E ∩ F)/P(F) where P(F) ≠ 0. 0 ≤ P (E|F) ≤ 1. P (E′|F) = 1 – P (E|F)
