Kimberly is a program director for the channel KID. She tracked the cartoons shown on the channel for a week. The probability that the show had animals in it was 0.7 . The probability that the show aired more than 10 times was 0.4. The probability that the show had animals in it and aired more than 10 times was 0.2. Which equation shows the correct use of the addition rule to determine the probability that a randomly selected show had animals in it or aired more than 10 10 times?

Step-by-step explanation:

If a media research company increased the size of their random samples from 3,500 to 5,000, to get the percentage margin error, we will follow the steps;

Initial sample size = 3500

Final sample size = 5000

margin error = Final sample size - initial sample size

Margin error = 5000-3500

Margin error = 1500

%margin error = Margin error/Initial sample size * 100%

%margin error = 1500/3500 * 100%

%margin error = 3/7 * 100%

%margin error = 300/7

%margin error = 42.86%

This means that they improved their margin by 42.9% (to the nearest tenth)
