How do we write the probability that someone is unemployed given they are in the 15-19 age group? 

Present the pivot table as "% of Column Total".

What is the probability that someone who is 15-19 years old is unemployed?

That is, what is ?

(Report as a probability to 4 decimal places, e.g. 0.6521)

You have previously calculated the probability that someone is unemployed given they are in the age group 15-19 and the probability they are unemployed given they are in the age group 45-49. 

What do these two probabilities indicate about the possible relationship between employment status and age group?  

Australia's unemployment rate for 15-19 year olds is 15%. If you were interested in comparing Timor-Leste's unemployment rate for 15-19 year olds with that in Australia, which presentation would be best for the pivot table?

What is the marginal probability that someone is in the age group 35-39?

That is, what is ? 

(Report as a probability to 4 decimal places, e.g. 0.6521)

Present the pivot table as "% of Row Total".

You will see that the first entry is 58.61%. What is the interpretation of this value? 

The values in the "% of Grand Total" pivot table can be interpreted as joint and marginal probabilities.

What is the joint probability that someone is in the age group 35-39 and unemployed?

That is, what is ? 

(Report as a probability to 4 decimal places, e.g. 0.6521)

Change the pivot table presentation to "% of Grand Total".

What percentage of men are employed? (Report to 2 decimal places and include appropriate units, e.g. 65.21%)
