The number of ways that you obtain a 2 on the black die is 6 ways.

If two fair dice(one black die and one white die) are rolled, in order to know the number of ways a 2 can be obtained on the black die, we will use the method of combination.

  • Combination has to do with selection. Hence the way a 2 can be obtained on a black die is 6C1

  • Note that a die has 6 faces and a 2 can only occur once in a toss.

Get the required number of ways:

6C1 =\frac{6!}{(6-1)!1!}\\6C1=\frac{6!}{5!1!}\\6C1=\frac{6\times 5!}{5!}\\6C 1=6 ways

Hence the number of ways that you obtain a 2 on the black die is 6 ways.
