Examples include the Monty Hall paradox and the birthday problem. Probability can be loosely defined as the chance that an event will happen.This leads to the result that: P(E ∩F) = P(E) ⋅P(F|E) P ( E ∩ F) = P ( E) ⋅ P ( F | E) The is an important result, called the Multiplication Rule, which will appear again in later sections. We now demonstrate the above results with a tree diagram. Example 4.5.3 4.5. 3. Suppose a jar contains 3 red and 4 white marbles.Step 1: Find the probability of a true positive on the test. That equals people who actually have the defect (1%) * true positive results (90%) = .009. Step 2: Find the probability of a false positive on the test.

The combinations of two children can be as ... young women's clothing Solution: The sum of probabilities of all the sample points must equal 1. And the probability of getting a head is equal to the probability of getting a tail. Therefore, the probability of each sample point (heads or tails) must be equal to 1/2. Example 2 Let's repeat the experiment of Example 1, with a die instead of a coin.results from each trial are independent from each other.

Explanation: Probability of each event = (# green marbles + # blue marbles)/ Total # of Marbles. P1 = (15 + 25) / 125 = 40 / 125. Second event assumes a blue or green was chosen for first event so there is one fewer marble on top and also one fewer marble in the total number of marbles.Since all of the events are mutually exclusive (one of the parties must win), you can get the probability of either D or R winning by adding their probabilities.
