| | 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. |
