Question

If two fair dice, one red and one white, are rolled, in how many ways can the result be obtained?

Answer 1

Answer:

C. 6 ways

Step-by-step explanation:

When two fair dice are rolled, the sample space of the outcome  is given below:

$(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)\\(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)\\(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)\\(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)\\(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)\\(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)$

Where in the pair (x,y), x represents the red die and y represents the white die.

The outcome in which the sum of the two dice is less than 5 are:

$(1,1) (1,2) (1,3) \\(2,1) (2,2) \\(3,1)$

Therefore, this result can be obtained in 6 ways.

The correct option is C.
