 | | Thus, the term 'expected value' may be defined as the sum of the products of the probability of each possible event and the value of that event multiplied by the sample size. |
 | | The calculation first determines the value of the 'average fish, ' given the $-unit slider settings for the population distribution by value, and then multiplies this value by the number of fish in an average sample of size 'height * width.' Thus, 'average value' * 'sample-size' = total is the expected value of sample. |
 | | As noted above, the relative ratios of the $1-fish, $2-fish, etc. in the lake are determined by relative values of all of the sliders on the left. |
