Answer 2

Probability is the prediction of the result of random experiment or event.

Example : We toss a coin (that is an random experiment), and have to find out what is the probability of getting a head as an outcome (result).

Its formula is :

$\frac{No. \: of \: favourable \: outcomes</p><p>[tex] \frac{No. \: of \: favourable \: outcomes}{ No. \: of \: total \: outcomes} \\ \frac{1 (a \: head)}{2 (total \: outcome)} \\ \frac{1}{2}$

So, 1/2 is the probability of getting a head.
