Answer:
a) 0.248
b) 0.434
Explanation:
Given;
Total number of Americans in the poll = 1000
Number of Americans not in favor of the bill = 434
Number of Americans in favor of the bill = 248
Number of Americans that were not sure = 318
a) We can now go ahead and determine the probability that a randomly selected American was in favor of the bill using the below probability formula;
[tex]Probability\text{ of an event occurring = }\frac{Number\text{ of favorable outcomes}}{\text{Total number of possible outcomes}}[/tex][tex]P(\text{Americans in favor of the bill) = }\frac{248}{1000}=0.248[/tex][tex]P(\text{Americans not in support of the bill) = }\frac{434}{1000}=0.434[/tex]
