Probability density functions can be used to determine the probability that a continuous random variable lies between two values, say a a and b b. 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.

Adding probabilities. 26 customers are eating dinner at a local diner. Of the 26 customers, 20 order coffee, 8 order pie, and 7 order coffee and pie. Using this information, answer each of the following questions. Let A be the event that a randomly selected customer orders coffee and B be the event that a randomly selected customer orders pie. Practice problem 2: Picking students. ... So, the probability of rolling an even number on a die is 3∕6 = 1∕2. Since the five dice are independent events, we can multiply their probabilities together, so the probability that all five dice show even numbers is (1∕2)⁵ = 1∕32.

To help us solve this problem, we can make a tree diagram to show all of the possible outcomes of rolling a die and flipping a coin: As shown from the diagram, we have possible outcomes, but there is only one way to roll a and for the coin to land on heads; thus, the probability isProbabilities may be marginal, joint or conditional. A marginal probability is the probability of a single event happening. It is not conditional on any other event occurring.Conditional probability using two-way tables. Researchers surveyed 100 students on which superpower they would most like to have.
