<em>Mean of the Population = 20 years and 6 months</em>
<em> = </em><em></em>
<em>Standard deviation of the Population = 2 years</em>
Let 'X' be the range of ages of the students on campus follows a normal distribution
Let x =21
<em>The probability of a randomly chosen student being exactly 21 years old.</em>

= 0.5 +0.793
= 1.293
