Often experiments are performed in order to produce observation or measurements that assists us in arriving at conclusion .these recorded information's in its original collected form are referred as " raw data"
MATHEMATICIANS define experiments as any process or operation that generate raw data .if a chemist run an analysis several times under the same experiment condition , he will not get concurrent result which will indicate an elements of chance in experiment procedure . it these chance outcome that occur around us with which probability is a basically concerned
RANDOM EXPRIMENT
AN Experiment whose all possible outcome are known in advance but outcome of any specific performance can not be predicted before the completion of experiment is known as random experiment
An example of random experiment might be tossing a coin , the experiment consists of only two outcomes head or tail .
Another example might be launching of a missile and observing the velocity at specific times . the opinion of voters concerning a new sales tax can be considered as outcome of random experiment
