Question

The probability of flipping a coin and getting tail is.

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

Answer 1

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

$\text{Sample space}$= $\left\{\text{H, T}\right\}$
$\therefore$ Number of equally likely outcomes= $2$
$\text{Favorable outcome}$= $\left\{\text{T}\right\}$
$\therefore$ Number of favorable outcomes= $1$

Hence, the probability of flipping a coin and getting tail is
$\text{P (tail)}=\frac{\text{Number of favorable outcomes}}{\text{Total number of equally likely outcomes}}$
$\Rightarrow \text{P (T)}=\frac{1}{2}$
