WebFor example, if you throw a die, then the probability of getting 1 is 1/6. Similarly, the probability of getting all the numbers from 2,3,4,5 and 6, one at a time is 1/6. Hence, the following are some examples of equally likely … WebAny ‘unconditional’ probability can be written as a conditional probability: P(B) = P(B Ω). Writing P(B) = P(B Ω) just means that we are looking for the probability of event B, out of all possible outcomes in the set Ω. In fact, the symbol Pbelongs to the set Ω: it has no meaning without Ω. To remind ourselves of this, we can write P= PΩ.
