Document Summary

Many things in our world depend on randomness: Even those events occur randomly, there is an underlying pattern in the occurrence of these events. Definition: a phenomenon is random if individual outcomes are uncertain but there is nonetheless a regular distribution of outcomes in a large number of repetitions. With a large number of observations, predictable patterns occur. Count red blood cells in a blood sample. An event is a subset of the sample space (or is the collection of one or more of the outcomes of an experiment) Give the sample spaces of above random phenomenon: Suppose you roll an unbiased die with 6 faces and observe the number on the upper face. Let a be the event of rolling 1 or 2. Let b be the event of rolling 3 or 4. Let c be the event of rolling an odd number. Let a be the event that occurs if at least a head is tossed.
