Question

A coin is tossed. What is the probability of getting:
(i) a tail?
(ii) a head

Answer 1

On tossing a coin once,
Number of possible outcome=2
(i) Favourable outcome getting a tail=1
$\Rightarrow$ number of favourable outcome= 2
$\therefore$ P(E) $\frac{Numberoffavourableoutcome}{Numberofallpossibleoutcome}$
$=\frac{1}{2}$
(ii) a head
Similarly, favourable outcome getting a head =1
But number of possible outcome= 2 $\therefore$ P(E) = $\frac{Numberoffavourableoutcome}{Numberofallpossibleoutcome}$
$=\frac{1}{2}$
