Solution:-
The probability of getting someone in the 22-29 age bracket or someone who responded is 0.8983.
Total number of people who responded = 344
Person in age of 22 - 29 = 251
Total number of persons who responded = 215 + 58 = 273
Number of person in 22-29 age bracket or someone who responded = 251 + 273 - 215 = 309
The probability of getting someone in the 22-29 age bracket or someone who responded = 309/344 = 0.8983
