Random walk in finance basically means that stock prices or security prices cannot be accurately predicted or guessed and hence all the tricks using CAPM OR any other way to create an ideal portfolio is just a myth. For Example: According to Random walk, the theory was that being an investor in the stock market what goes into my mind cannot be predicted by any finance theory, hence my behaviour in the future which decides the price of the stock ( whether to go up or down ) cannot be predicted. ITS A NEW DAY AT THE STOCK EVERYDAY.

Distance = Speed x Time You need to make a number of assumptions to get an answer. Let's assume that the average person walks about 2 miles per hour, and that they walk at this rate without stopping for the full 100 miles. Time = 100 Miles / 2 mph = 50 hours Make you own assumptions and calculate the results.

Non-probability or Judgement Samples has to do with a basic researcher assumptions about the nature of the population, the researcher assumes that any sample would be representative to the population,the results of this type of samples can not be generalized to the population(cause it may not be representative as the research assumed) and the results may be biased. Probability or Random samples is a sample that to be drawn from the population such that each element in the population has a chance to be in the selected sample the results of the random samples can be used in Statistical inference purposes
