      - with the logic all the scores, which are appearing once in the table will have same probability, which is 1/181 = 0.005525.
      Where as in your example, the probability for each score changed & when plotted, it showed a normal distribution.

      Is there any difference in "Mathematical Probability" & "Statistical probability"? Pl advise.

        We are using the formula for Normal Distribution here.

      Hi Sonal,

      I have a query from yesterday's lecture - where the scores were analysed (10-100(step0.5)- 181 records) thru NORM.DIST function.

      As per the mathematical knowledge, any event which the chance of occurrence is 1 & is equally likely to happen, the probability will be 1/(no. of events possible)
