<p>The circle graph showed 4 sectors, 20% reported Never, 15% reported Daily, 25% reported weekly, and 40% reported monthly.</p>
<p>The circle graph above shows the distribution of responses to a survey in which a group of people were asked how often they visit a certain weather Internet site. What fraction of those surveyed reported that they visit the site at least monthly?</p>
<p>I remember doing the "at least " thing in probability in Algebra 2, but I completely forgot the its concept and how to use it on this question. I came up with 2/5, which was, of course, wrong. The correct answer was 4/5. Can someone show me how to do this type of problem?</p>
<p>Thanks</p>
