Question:
A coin is tossed once. What is the probability of getting a tail?
Solution:
When a coin is tossed once, the possible outcomes are H and T.
Total number of possible outcomes = 2
Favourable outcome = 1
$\therefore$ Probability of getting a tail $=P(T)=\frac{\text { Number of favo u rable outcomes }}{\text { Total number of possible outcomes }}=\frac{1}{2}$
