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.
