A = 10 P(A) = 0.5 B = 20 P(B) = 0.4 C = 100 P(C) = 0.1 When we are saying P(A) = 0.5 and the same for every other variable. Are these the experimental probabilities or they are the theoretical ones? And to make things clear, does this mean that for example we made 10 trials and we resulted 5 in the first 4 in the second and one the last, did I get that correctly?

Hey Omar, Thank you for reaching out! Regarding your first question, these probabilities are simply some values that the lecturer has chosen for the purposes of the example - they aren't derived from anywhere, but rather made up. To answer your second question - yes, you are correct. However, bear in mind that these are just probabilities. You are not necessarily guaranteed that you will hit the bull's eye in one of 10 hits but it is probable that it will happen. Hope this helps! Kind regards, 365 Hristina
