P(A) ≥ 0, for all A(nonnegativity) 2. P(Ω) = 1 (normalization) 3. If Aand B are disjoint (A∩B= ∅), thenThis 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.

An experiment consists of drawing one card from a well shuffled deck of 52 cards. Consider the events E: the card is red, F: the card is a five, and G: the card is a spade.It is possible for a card to be both red and a five at the same time but it is not possible for a card to be both red and a spade at the same time.Preparing your children, grandparents and the family pet for the arrival of a newborn can be challenging.

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.Rosalyn is a teacher who plays a review game with her class. The game involves writing each student's name on an identical slip of paper and selecting students at random.
