a.
To find: The percentage of passengers who died.
The percentage of passengers who died is
Given:
Fate of Titanic Passengers:
Calculation:
The percentage of passengers who died is passengers is passengers who died over all passengers.
In the table,
Passengers who died
And total number of passengers
Conclusion:
The percentage of passengers who died is
b.
To find: The percentage of people were first-class ticket holders who died.
The percentage of people were first-class ticket holders who died is
Given:
Fate of Titanic Passengers:
Calculation:
The percentage of people were first-class ticket holders who died is number of passengers who died are in first class over the total number of passengers.
In the table:
Number of passengers who died are in first class =
And total number of passengers
Conclusion:
The percentage of people were first-class ticket holders who died is
c.
