Answer
a. 0.202
b. 0.696
c. 0.2404
d. 0.0402
Work Step by Step
a. P(USA) = $\frac{1557}{7690}$ = 0.202
b. P(high school or lower) = P(high school) + P(primary) = $\frac{4195}{7690} + \frac{1161}{7690}$ = 0.696
c. P(France or postgrad) = P(France) + P(postgrad) - P(France and postgrad)= $\frac{1539}{7690} + \frac{379}{7690} - \frac{69}{7690}$ = 0.2404
d. P(France and primary) = $\frac{309}{7690}$ = 0.0402
