Mathematicians and scientists generally come to know the meaning of probability at a much latter stage of learning and research instead of getting it within the first two years in college or university. This work involving some random experiments with coins and dice, is an attempt to give first or second year students in the university a classroom demonstration of the approaches to the definition of probability and some of the possible drawbacks in these definitions. We have also used outcomes of the experiments to test for unbiasedness of the die and coin. All results have shown that the devices are unbiased.
Key words: Probability, random experiments, unbiasedness.
