PROBABILITY I

Sample Space

Important concept:

·         An experiment is a process or action to observe its outcomes.

·         A sample space is the set of all possible outcomes from an experiment. It can be represented in the form of set notation.

·         Example : S ={(1,2),(1,3),(1,4)}

Example 1

Experiment: Tossing a fair coin

Sample space,

 S = {Head, Tail}

Example 2

Experiment:  A fair six-sided die is rolled.

Sample space, S ={1,2,3,4,5,6}

Example 3

Experiment: Drawing a ball from a bag containing three balls of the same size: white, black and green.

Sample space, S = {white ball, black ball, green ball}

LINEAR EQUATIONS

3.1 Solutions of Linear Equations in One Unknown

·         Solve linear equations = Finding the value of the unknown which satisfies the equation.

·         The solution of the equation is also known as the root of the equation.

·         A linear equation in one unknown has only one root.

·         To determine whether a given value is a solution of an equation, substitute the value into the equation. If the sum of the left hand side (LHS) = sum of right hand side (RHS), then the given value is a solution.

3.2 Solving Linear Equations in One Unknown through the operations  +,  –   ,   and

            There are 4 different forms of linear equation as follows :

Type	Equation	Operation	Solution
I	x + a = b	–	x = b – a
II	x – a = b	+	x = b + a
III	ax = b		x =
IV			x = a b
