Math notes grade 6

• Experiment


  Any activity or situation that can be done and leads to results or outcomes
• Possible outcomes


  The results of an experiment
• We use listings or diagrams to show the possible outcomes of an experiment
• Probability of a favorable outcome (E)

  number of favorable outcomes (E) / total number of possible outcomes
• A rate is a ratio that compares two different kinds of units
• Water consumption is measured in cubic meters (m³) over a specific period of time
• Water consumption is measured in cubic meters (m³) over a specific period of time
• The find the consumption, subtract the previous reading from the present reading
• Kilowatt-hours(kWh) is 1000 watts
• The probability of event is obtained by using the formula number of outcomes/number of trials
• Probability


  A measure of the chance that an event or outcome will happen. It is the ratio of the number of favorable outcomes to the number of possible outcomes.
• Calculating probability


  P(E) = number of favorable outcomes / number of all possible outcomes
• Experimental probability


  Based on the actual trial of the experiment
• Theoretical probability


  Based on the expected results of the experiment
