Question
The image displays a contingency table from a survey of 1,000 bottled beverage consumers. The table is organized as follows:

|                            | Lives in a state with a deposit law | Lives in a state with no deposit law | Row Total |
|----------------------------|-------------------------------------|-------------------------------------|-----------|
| Recycles beverage bottles  | 156                                 | 170                                 | 326       |
| Does not recycle beverage bottles |  58                          | 616                                 | 674       |
| Column Total               | 214                                 | 786                                 | 1,000     |

Below the table, several parts require calculation of probabilities or percentages based on the given data:

(a) **Probability that a consumer recycles beverage bottles.**  
   _Round your answer to 2 decimal places._

(b) **Probability that a consumer who lives in a state with a deposit law does not recycle.**  
   _Round your answer to 2 decimal places._

(c) **Percentage of consumers who recycle and live in a state with a deposit law.**  
   _Round your answer to 1 decimal place._

(d) **Percentage of consumers in states with a deposit law who recycle.**  
   _Round your answer to the nearest whole percent._
