- 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.
1. Sonal Ghanshani_1
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)

I created a datafame as shown below. I have to add another name in index and update scores; how to append it to existing data? I have to add 'Pandey' in index and Test1 = 56 and Test2 = 76

test_score = pd.DataFrame({'Test1':[82,75,83,92,85],'Test2':[85,81,75,85,91]},
index =['Sachin','Dravid','virat','Rohith','Dhawan'])
