Question

Think of something that you might want to measure that is affected by random variation. Identify what you want to measure, then describe its (approximate) sample space. Give a rough description of the probabilities associated with those values (you can simply specify if they are all the same probability or if values in one range will be more likely than values in another range). What would you say to a person who says that he or she "knows" what the outcome of an individual observation will be (an outcome of something that has not happened yet that is subject to random error)?

Explanation / Answer

Solut

For example if we throw a coin then probablity of event head or tail will be 1/2 or if we roll a dice then probablity of getting 1,2,3,4,5 and 6 will be 1/6. Hence in this example both of cases probablity are equal for each event.

But if we have a 4 white ball and 5 black ball in containor then probablity of drawing white ball is 4/9 and probablity of black ball is 5/9. Therefore in this example probablity are not equal for white and black ball.

Hence probablity is affected by random variation.
