A six-sided number cube is labeled with the numbers 1β6, one number on each face. Each number is used exactly once. How many possible outcomes exist when the cube is rolled two times?
Question
Answer:
Answer:36Step-by-step explanation:When the cube is rolled two times Let (a,b) denote a possible outcome of rolling the cube twice , with a the number on the top of the first roll and b the number on the top of the second roll(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)
(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)
(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)
(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)
(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)
(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)
There are 36 possibilities for (a,b).It can be obtained from the multiplication principle: there are 6 possibilities for a, and for each outcome for a, there are 6 possibilities for b. So, the total number of outcomes (a,b) is [tex]6 \times 6 =36[/tex]Hence the total number of possible outcomes is 36
