The daily lives of almost all people around the world are influenced by several quantitative data such as percentage, graph, chart, forecast, trend line and many others (Olson, 2007). Probabilities, uncertainties and chances are part of most of the decisions of every individual. In the daily lives of people, probabilities influence their small decisions such as clothes to wear or whether to take umbrella or not. Probabilities also affect larger decisions of individuals such as decisions regarding health, insurance jobs, financial matters and parenthood. In general, most of the decisions could be based on probabilities which are acquired every day. It could come from the media or from any other sources (Folks, 1981).
Probabilities could be used in small decisions of every individual (Folks, 1981). One major example of the use of probability is small decisions is during examinations or tests. Students often use probability in studying or preparing for examinations. Students could analyse the random properties of examinations given by teachers. One of these random properties is the probability regarding the appearance of specific questions on tests. Student could also use probability during the examination proper (Olson, 2007). Students could be able to pick or choose the best answer using probability. They could also use probability in order to decide which part of the examination they should focus.
Probabilities could also be used in larger decisions of individuals such as decisions regarding safety. For example, when driving a car, drivers often avoid roads which have many cases of accidents. Even when going home, people often think about the random chance of getting home safely (Olson, 2007). For example, people tend not to go home alone when they hear cases about people getting mugged.
