Answer:
Here, 16 % of the total population of a large country is hopelessly romantic. 
.
Assuming events are independent, 
Probability of a person who is hopelessly romantic = 16% = 16/100
(a) Probability of both will be hopelessly 
romantic =

Probability that are not hopelessly
 romantic = 100% - 16%= 84%
