Question
Explain the equi-probable events with illustration.
✓
Answer
If there is no apparant reason to believe that out of one or more events of a random experiment,
any one event is more or less likely to occur than the other events, then those events are called equi-probable.
Illustration: In the random experiment of tossing a balance coin, two events of getting head $(H)$ and getting tail $(T)$ are equi-probable,
$\text { because } P(H)=P(T)=\frac{1}{2}$
