• In probability: p(event)=outcomes matching event/total outcomes
• Experimental Probability: number of successful outcomes/number of trials
• 3/4 of 32 = 24
• A quadratic expression is one where the highest power of an algebraic term is 2
• The coefficient of an algebraic term is the number/constant in front of it. So the coefficient of 3x² is 3 and the coefficient of 5x³ is 5
• A constant term is one without any variables in it. So in 3x²+x+5, the constant term is 5.
• negative x negative = positive
• positive x negative = negative
• positive x positive = positive
