Lecture 9.2 - Expectation of a random variable

[@Harmansin13]

Is it like law of large numbers ?

[@d.youtubr]

Two different formulas are used for the 100 and 1000 case

[@Ashok-q4w]

Nope, you neeed to divide the total winning by total frequency.. In first case, total frequncy is 100 and in second case its 1000..

We have to multiply the Frequency column values with the wining column values, add them and finally divide by 100
