# Determine the probability P,for each of the following events.An odd number appears in a single toss of a fair die.

$\begin{array}{1 1}(A)\;\large\frac{1}{2}\\(B)\;\large\frac{1}{4}\\(C)\;\large\frac{1}{6}\\(D)\;\large\frac{1}{8}\end{array}$

Odd number appearing in a single toss of a fair die.
$\therefore$ Sample space S=6
P[odd number appearing in a single toss of a fair die]
$\Rightarrow \large\frac{n(E)}{n(S)}$
Whereby $n(E)$={1,3,5}
$n(S)=6$
$P=\large\frac{3}{6}=\frac{1}{2}$
Hence (A) is the correct answer.
