Which of the following statements is TRUE?
Nothing is wrong with the data. In fact, the set "X and Y" equals {1,2,4,5,6}.
Something is wrong with the data because set X contains four items that are out of order.
Something is wrong with the data because set Y contains two items that are the same.
Nothing is wrong with the data. In fact, the set "X or Y" equals {1,2,4,5,6}.
X = {4,1,5,6} Y = {2,5,6,6}Explanation / Answer
Since the outcomes of rolling a dice can fall from 1 to 6, both the outcomes are correct, also, exhaustive set is {1,2,4,5,6}. thus option D is correct
