According to u. s. census bureau figures, 35.3% of all americans are in the 0-24 age bracket, 14.2% are in the 25-34 age bracket, 16.0% are in the 35-44 age bracket, and 34.5 are in the 45 and older age bracket.
a study by jupiter media metrix determined that americans use their leisure time in different ways according to age.

for example, of those who are in the 45 and older age bracket, 39% read a book or a magazine more than 10 hours per week. of those who are in the 0-24 age bracket, only 11% read a book or a magazine more than 10 hours per week.
the percentage figures for reading a book or a magazine for more than 10 hours per week are 24% for the 25-34 age bracket and 27% the 35-44 age bracket. suppose an american is randomly selected and it is determined that he or she reads a book or a magazine more than 10 hours per week.
revise the probabilities that he or she is in any given age category. using these figures, what is the overall percentage of the u. s. population that reads a book or a magazine more than 10 hours per week?
