"Initially, I tried solving using variables, but as a blind person, this became too difficult to manage in my head. Since only a fraction was required, I arbitrarily chose a number for the people wearing all three items and proceeded from there. I also assumed there were no people waring none of the items, since this would make it impossible to determine a fraction.
Assume there are 100 people who wear all three items. Then, there are 400 people wearing hats, 500 people wearing scarfs, and 600 people wearing gloves. We also know that there are 200 people wearing only two items. The rest must be waring only one item. Since we do not care which two items are being worn, let’s assume that 200 people wearing hats also wore scarfs. That leaves 100 people wearing only hats, 200 people wearing only scarfs, and 500 people wearing only gloves. Adding these all together: 100 all three, 200 only two, 100 hats, 200 scarfs, and 500 gloves equals 1100 people in total. Therefore, one in 11, or approximately 9%, of the total group wore all three items.
