1. A sample topographic point includes the set of simple take downts of an experiment. All possible outcomes ar included. For instance, call for the experiment of me take cereal for breakfast. Possible outcomes may be eating cereal for breakfast, non eating cereal for breakfast, and not eating breakfast.
There are 3 prospect producements. That marrow there is more than one valid way to assign probabilities to a sample space. One way is an appellative found on intuition. One may think of past experiences, concept or an opinion in the likelihood of an event occurring. other way is ground on relative frequence. The formula utilize for relative frequency is f/n where f is the frequency of the event occurrence in a sample of n observations (Brase 132). The last way is a probability assignment based on equally likely outcomes. The formula used is the deem of outcomes favorable to event/Total number of outcomes ( Brase 132). For my experiment on eating cereal for breakfast, I digest use the probability assignment based on intuition where I can incorporate my past experiences on breakfast. I can consider what I ate the day before or even a week before.



If I had cereal yesterday, I near likely am going to have cereal today. If my assignment is based on relative frequency, I could say the P (eating cereal for breakfast) is 3/7 which is .43. This means that the chance of me eating cereal for breakfast is 43%. For an assignment based on equally likely outcomes, the P (eating cereal for breakfast) is 1/3 or 33%.
With the Law of Large gets, as the sample size increases and increases, the relative frequencies of outcome get closer to the essential probability value (Brase 134). If probabilities are equally likely than the outcomes are equally likely to occur, to compute this I use the formula, Number of favorable outcomes/Total number of outcomes (Brase 132).
