      such sequences. Ergo, the probability of 4 heads in 10 tosses is 210 * 0.0009765625 = 0.205078125. We can now write out the complete formula for the binomial distribution: In sampling from a stationary Bernoulli process, with the probability of success equal to p, the probability of observing exactly r successes in N independent trials is p q

      Any ‘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.
