In one town 44% of all voters are Democrats if two voters are randomly selected for a survey find the probability that they are

kenny6666 [7]

Answer:

0.194

Step-by-step explanation:

Probability that BOTH are democrats means probability of <u>"one being democrat"</u> AND <u>"another also being democrat"</u>.

The AND means we need to MULTIPLY the individual probability of a person being democrat.

Probability that a voter is democrat is 44% (0.44) -- stated in the problem

Now, Probability BOTH being Democrats is simply MULTIPLYING 0.44 with 0.44

$0.44*0.44=0.1936$

Rounded to nearest thousandth, 0.194

Last answer choice is correct.

Steps to solve this-- Find the percent of increase from 380 to 440. Round to the nearest tenth of a percent if necessary. 13.6%

OLga [1]

If 380 would be 100%

Then use rule of 3

380 ______ 100%

440 ______ y

380y = 440×100%

380y = 440 × 1

Dividing both the sides by 380

y = 440/380

y = 1,158

Let's multiplity "y" by 100

y = 115,8%

As we did have 100% initially

Then the increase will be

The increase = 115,8% -100%

= 15,8%

This would your answer
