probability of them both occurring at the same time is 0. Disjoint: P (A and B) = 0 If two events are mutually exclusive‚ then the probability of either occurring is the sum of the probabilities of each occurring. Specific Addition Rule Only valid when the events are mutually exclusive. P (A or B) = P (A) + P (B) Example 1: Given: P(A) = 0.20‚ P(B) = 0.70‚ A and B are disjoint I like to use what’s called a joint probability distribution. (Since disjoint

association between addition and multiplication is that multiplication is a shortcut to repeated addition. In other words‚ it is adding similar numbered groups using multiplication as an alternative. Understanding that multiplication and repeated addition are related will help extend the students use of multiplication. They will understand that when grouping items they can use multiplication to achieve the same answer in a shorter amount of time. One method I can use to teach repeat addition and multiplication

Introduction to College Algebra November 9‚ 2009 2 Chapter 1 Sets Definition 1.1. A set is a well-defined collection of distinct objects. Each object in a set is called an element of the set. By “well-defined”‚ we mean that the rule of membership to the set is clear. Example 1.2. The following are examples of sets. 1. The set of counting number less than 5. 2. The set of vowels in the word “mathematics”. 3. The set of cities in the Philippines. 4. The set of positive integers from −2 to

The two properties of integer arithmetic are as follows a) Result of any arithmetic operation is an integer b) Result is always exact with two exceptions • Range of integer that can be represented is not infinite but is bounded above and below. • The result of the division operation is given as the combination of the quotient

is used to simplify expressions. Explain specifically the order in which mathematical operations must be performed to correctly simplify an expression. The order of operations is a rule that always applies to mathematical problems. It includes addition‚ subtraction‚ multiplication and division as well as grouping of numbers (such as in parentheses and powers). It gives a definite order of how to do a problem involving multiple operations. Without these cut and dry rules that the order of operations

Part 1 2 The Summative Assessment Design is to develop the students with addition and subtraction by having multiple strategies to addition by placing together and understanding‚ and also to understand the subtraction in taking from and taking apart. Each student will be able to demonstrate the understanding of joined addition and/or separated subtraction of its objections by demonstrating addition and also subtraction in different ways. With the assessment plan it will measure the student’s

As mentioned earlier VAT is nothing but a form of sales tax only and is charged at each stage of sale on the value added to the goods. “Value Added” is the difference between sale and purchase of a business. A straight forward way to compute the base of a VAT for a given period‚ say a quarter‚ is‚ in the case of a manufacturer‚ to deduct the total
