If shipments increased by 7% (which is the same as 0.07) per year, then the shipment in a year can be found by multiplying the shipments in the previous year by 1.07.
Therefore, if represents the number of years since 2000 and represents the number of shipments, then .
First two rolls have to be 1-4 that is 2/3 chance twice and the third can be 4or 5 2/3*2/3*1/3 + the chance that the fourth is the 5 or 6. 2/3*2/3*2/3*1/3
So the solution is : P=2/3*2/3*1/3 + 2/3*2/3*2/3*1/3
I think she can add 5p more of orange which is 9p and 6p more water which is 8p. I'm pretty sure this works because 9 is the next closest multiple of 3 and 8 is one number less than that. Hope this helps!
