WebLet X be uniformly distributed. Then the expected value is the sum of all outcomes, divided by the number of possible outcomes. For the die example we saw that P (X=x) = 1/6 for all possible outcomes. Then E [X] = (1+2+3+4+5+6)/6 = 3.5. Here you see that the expected value does not need to be a possible outcome. WebIn other words, the 2024 budget is at most as large as the 2024 budget. a) For any given value of x(50<350), obtain E[Y X=x] b) In view of part (a), obtain E[Y X] c) Atlanta Braves won the 2024 World Series title.
