The 0.14 is because the probability of A and B is the probability of A times the probability of B or 0.20 * 0.70 = 0.14. Dependent Events. If the occurrence of one event does affect the probability of the other occurring, then the events are dependent.

Addition and Multiplication Rules for Probability Worksheet Addition Rule I. Determine whether these events are mutually exclusive. 1) Roll a die: get an even number and get a number less than 3 2) Roll a die: get a prime number and get an odd number 3) Roll a die: get a number greater than 3 and get a number less than 3 4) Select a student in the classroom: student has blond hair and blue... When we use the word and we are referring to multiplication. to find the probability of that event: Thus it follows that: But remember from set theory that and from the way we defined our sample space above: . and so the probability that event B occurs given that event A has occurred is the same as the probability of event B. Additive Rule (A∪B) In probability we refer to the addition

The addition law As we have already noted, the sample space S is the set of all possible outcomes of a given experiment. Certain events A and B are subsets of S. In the previous Section we deﬁned what was meant by P(A), P(B) and their complements in the particular case in which the... Probability : Addition and Multiplication Rules.

- When we use the word and we are referring to multiplication. to find the probability of that event: Thus it follows that: But remember from set theory that and from the way we defined our sample space above: . and so the probability that event B occurs given that event A has occurred is the same as the probability of event B. Additive Rule (A∪B) In probability we refer to the addition
- Addition rules are important in probability. These rules provide us with a way to calculate the probability of the event "A or B," provided that we know the probability of A and the probability of B.

- Put in words, the rule asserts that the joint probability of A and B, P(AB), is equal to the conditional probability of A given B, times the (unconditional) probability of B. Example 1 The probability of relaxed import restrictions is 0.5.
