### A coin is tossed once. What is the probability of getting a head.

$\dfrac { 1 } { 2 }$

Step by Step Explanation:
1. When a coin is tossed once, the possible outcomes are head and tail.

Let $E$ be an event of getting a head.

Total number of possible outcomes = $2$.

The favourable outcome is a head.

So, the number of favourable outcomes = $1$

\begin{aligned} \therefore P(\text{ getting a } head) = P(E) = \dfrac { \text{ Number of favourable outcomes } } { \text{ Total number of possible outcomes } } = \dfrac { 1 } { 2 } \end{aligned}
