Hi all, 3. The probabilities are 0.06, 0.21, 0.24, 0.18, 0.14, 0.10, 0.04, 0.02 and 0.01 that an airline will receive 0,1,2,3,4,5,6,7 or 8 complaints per day about its luggage.Find
e(x) and e(x^2) Give the R commands you use and the two numerical values. Use the sample function to simulate complaints over 500 days. Give the R command you use and draw a barplot of the simulated data. Comment on how the pattern you see relates to the probabilities in the question above. I think i have done the first part and got e(x) = 2.75 and e(x^2)= 10.59 I have no idea how to simulate complaints over 500 days and draw a barplot. can anyone help?
