Answer:

a) 0.248

b) 0.434

Step-by-step 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;


Probability\text{ of an event occurring = }\frac{Number\text{ of favorable outcomes}}{\text{Total number of possible outcomes}}


P(\text{Americans in favor of the bill) = }(248)/(1000)=0.248


P(\text{Americans not in support of the bill) = }(434)/(1000)=0.434
