Probability is a numerical description of how likely an event is to occur or how likely it is that a proposition is true. Probability is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility and 1 indicates certainty.
In this topic, we cover the following: Bar charts and pie charts, experimental probability, theoretical probability, combined probability, outcome tables and tree diagrams and addition & multiplication laws of probability. At the end of this topic, students should understand the following among other things:
- Recall previous knowledge to use the language of probability, including applications to set language, to describe and evaluate events involving chance,
- Define and use experimental probabilities to estimate problems involving chance,
- Define and use theoretical probabilities to calculate problems involving chance,
- Solve problems involving combined probabilities,
- Illustrates probability spaces by means of outcome tables, tree diagrams, Venn diagrams, and use them to solve probability problems,
- Solve mathematically problems that relate statistics to probability such as drawing histogram of a distribution, calculating mean mass and stating modal class etc.,
- Construct a cumulative frequency table and use ogive to determine percentile,
- Solve complex examination probability questions.
Again, a student should understand
- tables, class intervals, histograms and frequency polygons,
- Apply previous knowledge to what is learn here to calculate, illustrate and interpret the mean, median, mode of grouped data and standard deviation of a set of discrete data,
- Construct and draw cumulative frequency tables curves and use them to deduce quantities and medians,
- Interpret the variation or spread of a data set in terms of its standard deviation,
- Select and use a working mean to simply calculation and calculate the variance of a given data set,
