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:

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

Answer:
S(x)=42000 * 1.04^x
Step-by-step explanation:
now = 42000
in 1 year = 42000 *1,04, because 4% increase is to multiply 1,04
in 2 years = 42000 *1,04*1.04 = 42000*1.04^2
in x years = 42000 * 1.04^x
