Algebra ->  Probability-and-statistics -> SOLUTION: Out of a group of elderly people 19 wear glasses,8 wear hear aids,6 wear both and 5 wear neither. How many wear exactly one of these two items mentioned? How many people are there       Log On

19 - 6 = 13 wear glasses only.


 8 - 6 =  2 wear hear aids only.


13 + 2 = 5 wear exactly one of these two items.


Total people = 13 + 2 + 6 + 5 = 26.
