<p><strong>11. Quadractic Quizzicality</strong></p>
<p><strong>Question: </strong>Suppose B and C are random numbers from a uniform(0,1) distribution. What is the probabilty that x^2 + Bx + C = 0 has two real roots?</p>
<p><strong>Solution:</strong> x has two real roots if its discriminant is greater than zero. i.e B^2 - 4C > 0. </p>
<p>So B^2 > 4C or c < B^2/4.</p>
<p>The sample space for B and C has an area of 1 and the area beneath the curve of C = B^2/4 represents the values for B and C that result in real roots.</p>
<p>So the probabilty that B^2 - 4C > 0 (the equation x^2 + Bx + C = 0 has two real roots) is the integral from 0 to 1 of B^2 /4 which is 1/12.<br />

<p>I've just visited www.mathsbusking.com. It comprises of:<br />
</p>
<p>"street performance, stage performance, entertainment at educational/scientific events, performer training sessions, teacher development and workshops for young people."</p>
<p>It sounds like great fun and it is definately something I wouldn't mind being invloved in. <br />

<p> "Divide fourteen sugar cubes into three cups of coffee so that each cup has an odd number of sugar cubes in it." <br />
"That's easy: one, one, and twelve." <br />
"But twelve isn't odd!" <br />
"It's an odd number of cubes to put in a cup of coffee..."</p>
