According to excel's calculations, there's a 0.05% chance that four randomly selected vehicles will be under my $66,000 average. The probability that it would be at least four cars, according to my spreadsheet's calculations, is 0.06%... but the probability that it's less than five is 3%... but the probability that it's more than 6 is 12%... so I guess I just don't understand this. IS THIS CORRECT
