Answer:
1/2 a bag
Step-by-step explanation:
1/2 a piece is smaller than 1/2 a bag because the bag is bigger
1/4 = 0.25
5/8 = 0.625
20% = 0.20
So now we have: 0.20 < 0.25 < 0.3 < 0.625 < 0.85
So the solution is 20%, 1/4, 0.3, 5/8, 0.85
This is a statistics problem on permutation and combination. To differentiate this, permutation involves on the arrangement in which order doesn't matter. For combination, order matters.
For example, if you arrange A, B and C, for permutation it could be AB, BA, CA, AC, BC and CB. But for combination, it would just be AB, AC and BC.
So, in this problem where he is asked to arrange 8 jars in which order doesn't matter. It is permutation. You can solve this just by calculator. The formula would be nPr, where n is the total number of items while r is the number of items to be sorted. Thus,
nPr = 10P8 = 1, 814,400
Thus, the answer is B.
