Question

A number from $1-19$ is chosen at random. Find the probability of choosing an even number.

• A. $\frac{4}{19}$
• B. $\frac{9}{19}$
• C. $\frac{8}{19}$
• D. $\frac{11}{19}$

Answer 1

Answer: (B)

$\frac{9}{19}$

Let the even number be $\{2,4,6,8,10,12,14,16,18\}=9$
Total number $=19$
$P$ (choosing an even number) $=$ $\frac{\text{Number space of space getting space even space numbers}}{\text{Total space number}}$
$=$ $\frac{9}{19}$
