Explanation / Answer

Solution:- The probability that the subject responded or is between the ages of 22 and 39 is 0.896.

==>

= (79 + 261 + 251 + 142 + 144 + 208) ÷ (79 + 261 + 251 + 142 + 144 + 208+ 12 + 21 + 34 + 27 + 36 + 58)

= (1085 / 1273)

= (21 + 34) ÷ 1243 = (55 / 1273)

  

= 0.896 (three decimal)
