Starting more simply, if we wanted to know how many students like pink in general, that's 68/100. We could do that for each single category and the fractions would add together to equal 1. Now say we wanted to know something about that 68/100 people. That 68 is our new 100%, or another way of looking at it is if we take however many people like pink and don't like black and those that do like black, they will equal 68/68.
The number of people that like pink but don't like black is 41/68 and those that like pink and black are 27/68. 27+41=68 For the question of your problem it is asking about those that do not like pink which you can tell from the table or use from my saying 68/100 like pink is 32. Now you can split that into those that do or don't like black, and the two results will equal 32/32.

To approximate the square root of 13:
Working from the top down...
Enter the number you are trying to approximate in the top box:
Find the perfect squares directly below and above 13.
Perfect squares: 1, 4, 9, 16, 25, 36, ...
Therefore, the perfect squares below and above 13 are: 9 and 16
Enter these with square root signs in the next two boxes:
and
Carry out the operation and enter
and
in the next two boxes.
Enter the number you are trying to square root (13) in the top left box, the perfect square above it (16) in the box below, then the perfect square below it (9) in the two boxes to the right of these. Carry out the subtractions and place the numbers in the boxes to the right.

Now enter the number you are trying to square root (13) under the square root sign. Place the square root of the perfect square below it (3) in the box to the right. Copy the fraction from above (4/7). Finally, enter this mixed number into a calculator and round to the nearest hundredth.

Hello from MrBillDoesMath!
Answer:
Choice E.
Discussion:
Assuming that n >=1, a(n) = 4n -1, then
a(10) = 4(10) - 1 = 39
but that doesn't match any of the answers...... hmm...
BUT
If you meant that a(n) = 4^(n-1), then
a(10) = 4^(10-1) = 4^9 = 262144
which is Choice E.
Thank you,
MrB
