Answer:29Step-by-step explanation:Given that:Bag 1 : Bag contains 10 tags numbered 1 - 10 with different numbers on eachBag 2: Another bag with 8 tags numbered from 20 - 27Two Tags are drawn at random, one from each bag; Expected value of the sum of numbers on the two selected tags :Expected value = mean of numbers in bag 1 + mean if numbers in bag 2E(X) = (bag 1 minimum + maximum) / 2 + (bag 2 minimum + maximum) / 2E(X) = [(1 + 10) / 2] + [(20 + 27) / 2]E(x) = (11/ 2) + (47/2)E(x) = 5.5 + 23.5E(x) = 29Hence, expected value of sum if numbers from each draw = 29...
