The formula for the Expected Value for abinomial random variableis: P(x) * X. X is the number of trials and P(x) is the probability of success. For example, if you toss a coin ten times, the probability of gett
and finally, "How shall we interpret the concept of expected or probable price?" The answer to the first and second question is no. The answer to the third question is that a frequency interpretation of probability should be rejected in valuation contexts, in favour of an interpretation where...
expected value- the sum of the values of a random variable divided by the number of values arithmetic mean,first moment,expectation statistics- a branch of applied mathematics concerned with the collection and interpretation of quantitative data and the use of probability theory to estimate population...
So, to calculate expected value, first multiply the probability of a positive outcome by the potential return. Say, an investment has a 60% chance of increasing in value by $10,000. The calculation would be: 0.6 x $10,000 = $6,000. ...

A probability distribution depicts the expected outcomes of possible values for a given data-generating process. Probability distributions come in many shapes with various characteristics. They're defined by the mean, standard deviation, skewness, and kurtosis. ...
