First, we need to find the total number of respondents:

Then:

Under 28 25

18-25 24

26-35 34

36-45 56

Over 45 54

Total = 25+24+34+56+54

Total= 193 total of respondets

Now, we need to find respondents that are 36 or older. then:

36-45 56

Over 45 54

n(36 or older)= 56 + 54

n(36 or older= 110 respondents that are 36 or older

Finally, the probability, in this case, can be found using:

P(36 or older)= n(36 or older)/ Total

Replacing on the equation:

P(36 or older)=110/193

So, the probability for the next respondent will be 36 or older is given by the fraction 110/193.
