Work Step by Step
a. The Asian group. We can see the dotted line for the number 100, and the Asian bar is the only one going over it. There's no way to have an exact estimate of the value from the graph, but a good one looks to be 122.
b. If we estimate that the number of people unable to read or write is 30. We can estimate that the number of people in the world who can't read or write is:
$30*33,000,000=990,000,000$
