Question

Find the probability of getting a head when a coin is tossed once. Also find the probability of getting a tail.

Answer 1

Let $S$ be the sample space of tossing a coin

$S=\{H,T\}$

Probability of getting head $=\frac{\text{no. of favorable outcomes}}{\text{no. of total outcomes}}=\frac{1}{2}$

Probability of getting tail $=\frac{\text{no. of favorable outcomes}}{\text{no. of total outcomes}}=\frac{1}{2}$
