<p><strong>Golf Putts</strong></p> <p>A golf tournament director recorded the number of putts needed on a hole for the four rounds of the tournament. The random variable x represents the number of putts needed on the hole. Decide whether the distribution is a probability distribution. If it is not a probability distribution, identify the property (or properties) that are not satisfied.</p> <table style="border-color: #0702fc; border-width: 2px;" border="2" frame="border" rules="all" cellspacing="2" cellpadding="2" align="center"> <tbody> <tr> <td style="text-align: center;">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mi»x«/mi»«/math»</td> <td style="text-align: center;">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mn»0«/mn»«/math»</td> <td style="text-align: center;">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mn»1«/mn»«/math»</td> <td style="text-align: center;">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mn»2«/mn»«/math»</td> <td style="text-align: center;">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mn»3«/mn»«/math»</td> <td style="text-align: center;">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mn»4«/mn»«/math»</td> <td style="text-align: center;">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mn»5«/mn»«/math»</td> </tr> <tr> <td style="text-align: center;">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mi»P«/mi»«mfenced»«mi»x«/mi»«/mfenced»«/math»</td> <td style="text-align: center;">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mn»0«/mn»«mo».«/mo»«mn»007«/mn»«/math»</td> <td style="text-align: center;">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mn»0«/mn»«mo».«/mo»«mn»292«/mn»«/math»</td> <td style="text-align: center;">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mn»0«/mn»«mo».«/mo»«mn»349«/mn»«/math»</td> <td style="text-align: center;">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mn»0«/mn»«mo».«/mo»«mn»245«/mn»«/math»</td> <td style="text-align: center;">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mn»0«/mn»«mo».«/mo»«mn»058«/mn»«/math»</td> <td style="text-align: center;">«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«mn»0«/mn»«mo».«/mo»«mn»004«/mn»«/math»</td> </tr> </tbody> </table>
