<p>I might self study this and i have googled some stats questions and I want to see if I am capable. I found most of themto be fairly easy, except this one.</p>

<p>There are 3 gray, 6 red, 2 orange, 2 blue, and 3 purple marbles in a hat. You pick 2 marbles from the hat. Marbles are not returned after they have been drawn.</p>

<p>P ( the first marble is orange, and the second marble is orange.</p>

<p>Are other AP questions normally worded like this? I dont understand this</p>
