Assuming order doesn't matter, we can use the probability formula nCr. Using a calculator, you get that there are 210 possible combinations. However, if order did matter, then you would use nPr, in which case would the answer be 5040.

Its 110 cuz it goes up 10% if it was 20% it would be 120
It should be C., is that what the graph looks like?
66.6667%
Now we can see that our fraction is 66.666666666667/100, which means that 4:6 as a percentage is 66.6667%.
Its A.........................................
