The $5-$kilometer asteroid Touta$-$tis passed a mere $1\mathrm{.}5$ million kilometers from Earth in $2004.$ Suppose Toutatis were destined to pass somewhere within $1\mathrm{.}5$ million kilometers of Earth. Calculate the probability that this "somewhere" would have meant that it slammed into Earth. Based on your result, do you think it is fair to call the $2004$ passage a "near miss"? Explain. $($Hint: You can calculate the probability by considering an imaginary dartboard of radius $1\mathrm{.}5$ million kilometers in which the bull's$-$eye has Earth's radius, $6378$ kilometers.$)$
