WebbAnswer Losing money means the return < 0%. When calculating probability, we represent this statement as P (X < 0) Step 1 – Calculate Z Score The first step is to standardize the target variable value into a standard normal random variable (Z Score) using the known standard deviation and mean. WebbSo, we would just take the number 1 and subtract the probability found in the table, which provides the probability of obtaining a value above the specified z-score. Lastly, to find the probability of finding a value between two z-scores, we take the probability of finding a value below the upper range and subtract the probability of finding a ... selling a musical jingle
