Answer:
E. 2700.
Step-by-step explanation:
There are 3 possible values for the first digit ( V, X or P)
The second and third have 10P2 = 10!/(10-8)! = 90 possible values.
The third digit - there are 10 possibilities
So the answer is 3 * 90 * 10
= 2700.
<u>Percentage equation:</u>
Current amount of money / Total amount of money
Total amount of money = 220
Amount of money spent = 35
Current amount of money = 220 - 35 = 185
185 / 220 = 0.840909.....

There are three ways to achieve the combination of one male singer, one female singer, and no voice instrumental
Male - Female - No Voice
Male - No Voice - Female
Female - Male - No Voice
Female - No Voice - Male
No Voice - Male - Female
No Voice - Female - Male
For each combination, the probabilities are
MFN = 0.45×0.4×0.15 = 0.027
MNF = 0.45×0.15×0.4 = 0.027
FMN = 0.4×0.45×0.15 = 0.027
FNM = 0.4×0.15×0.45 = 0.027
NFM = 0.15×0.4×0.45 = 0.027
NMF = 0.15×0.45×0.4 = 0.027
Then add all the probabilities we have 0.027×6 = 0.162
120% of 65 is 78.
This means that 120 times what equals 78.
120*65=78
