Question

the probability of any event can never be less than 0 or more than 1.Give relation

Answer 1

$probability = \frac{number \: of \: favourable \: outcomes}{total \: number \: of \: outcomes}$
from the of relation we can so that

The number of favourable outcomes can never be less than zero so the probability can also not be smaller than zero.

The number of favourable outcomes are always less than the total number of outcomes so the probability cannot be greater than 1.
