WebLet's consider three positive numbers x, y and (1-x-y). For 1-x-y to be positive 1-x-y>0 or x+y<1 Note that when x+y>1 then 1-x-y <0 ( a negative quantity) and so the product xy (1-x-y) will be negative So we only need to prove this result for the case x+y<1 Now by AM GM inequality [x+y+ (1-x-y)]/3 >= [xy (1-x-y)]^1/3 Or, 1/27 >= xy (1-x-y) WebExample \(\PageIndex{1}\) For an example of conditional distributions for discrete random variables, we return to the context of Example 5.1.1, where the underlying probability experiment was to flip a fair coin three times, and the random variable \(X\) denoted the number of heads obtained and the random variable \(Y\) denoted the winnings when …
