Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 99 people
sertanlavr [38]

Answer:

The probability of getting someone in the 18-21 age bracket or someone who agreed to respond = 0.365

Step-by-step explanation:

The counts are as follows  

Age Group  No of people contacted No of refusals      Total  

18-21               88                                  8                       96

22-29              240                                  42                       282

Total              328                                  50                       378

 

The probability of getting some one in the age bracket of 18-21 or some one who refused to respond is

= \frac{96}{378} + \frac{50}{378} - \frac{8}{378} \\= \frac{96+50-8}{378} \\= \frac{138}{378} \\= 0.365
