Question

In a certain year, congress began debating a new health care bill. A poll of 1000 Americans at the time indicated that 434 opposed the bill, 248 favored the bill, and 318 were not sure. Based on these results assume you ask a randomly selected American this question. Express your answers as exact decimals. a) What is the probability that a randomly selected American was in favor of the bill?b) What is the probability that a randomly selected American was not in support of the bill?

Answer 1

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;

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

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

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