No. of persons in the car	$1$	$2$	$3$	$4$	$5$
No of Cars	$22$	$16$	$12$	$6$	$4$

Suppose another car passes by after this time interval. Find the probability that it has only $2$ persons sitting in it

• A. $\frac{4}{15}$
• B. $\frac{12}{15}$
• C. $\frac{13}{15}$
• D. None of these

$P$(having $2$ person) $=\frac{No.OfPerson2}{Total}$ $=\frac{16}{60}=\frac{4}{15}$
