Answer 1

We have the next given information:

Total of people = 1,000

428 opposed the bill

220 favor of the bill

352 were not sure.

To find the probability that randomly selected Americas was in favor of the bill, we need to use the probability formula:

$P=\frac{Number\text{ of}favorable\text{ outcomes }}{total\text{ number of outcomes}}$

Where

# of favorable outcomes = people who was in favor of the bill = 220

Total number of outcomes = 1000 people who
