Question

A number from $2$ to $13$ is chosen at random. What is the probability that the number chosen is not even?

• A. $\frac{1}{5}$
• B. $\frac{3}{4}$
• C. $\frac{5}{6}$
• D. $\frac{1}{2}$

Answer 1

The correct option is D $\frac{1}{2}$

$P$ (getting odd number) $=$ $\frac{6}{12}=\frac{1}{2}$

$P$ (getting not an even number) $=1-P$ (getting odd number)$=$ $1-\frac{1}{2}=\frac{1}{2}$
