Before Transferring oil to Tank C :
Tank A = n
Tank B = n + 150
Tank C = 0
Total = n + n + 150
Total = 2n + 150
After transferring some oil to Tank C, each of the tank has the same amount.
Each tank = (2n + 150) ÷ 3 = 2/3 n + 50
500ml was transferred from tank A to Tank C:
n - (2/3n + 50) = 500
n - 2/3n - 50 = 500
1/3n = 550
n = 1650 ml
----------------------------------------------------------------------------------------
Answer: The value of n is 1650.
----------------------------------------------------------------------------------------
Check:
Before Transfer:
Tank A = n = 1650
Tank B = n + 150 = 1650 + 150 = 1800
Tank C = 0
Total = 1650 + 1800 = 3450ml
After transfer:
Each tank = 3450 ÷ 3
Each tank = 1150
Tank A before transfer = 1650
Tank A after transfer = 1150
1650 - 1150 = 500 (checked)

Answer:
0.4833
Step-by-step explanation:
We want GIVEN THAT 200 pages or MORE AND RETURNED ON TIME.
Returned on time
fewer than 200 pages—— 78
200 pages ir more ——116
Returned late
Fewer than 200 pages ——15
Returned late ——31
The first table is returned on time and last row is 200 pages or more, so we take that value "116".
To get probability, we also need the total. We add up all those 4 values:
78 + 116 + 15 + 31 = 240
Thus, probability is = 116/240 = 0.4833
