This probability is denoted by P (a ≤ X ≤ b) P ( a ≤ X ≤ b) and is given by, P (a ≤ X ≤ b) = ∫ b a f (x) dx P ( a ≤ X ≤ b) = ∫ a b f ( x) d x. Let’s take a look at an example of ... Find the probability. This problem requires us to find the probability that p1 is less than p 2. This is equivalent to finding the probability that p 1 - p 2 is less than zero. To find this probability, we need to transform the random variable (p 1 - p 2) into a z-score. That transformation appears below.
