In a cricket match a batsman hits boundary 4 times out of 30 balls, he plays find the probability that he did not hit a boundary

Answer 1

p(hitting)=4/30
p(not hitting)=1-4/30=26/30=13/15

Answer 2

Some experiments related to PROBABILITY :

$\underline{ \large { \bold{Experiment:}}}$

An operation which can produce some well-defined outcomes, is called an experiment.

Each outcome is called an event.

$\underline{ \large { \bold{Random\:Experiment:}}}$

An experiment in which all possible outcomes are known and the exact outcome cannot be predicted in advance, is called a random experiment.

$\underline{ \large { \bold{Empirical \: Probability :}}}$

Suppose we perform an experiment and let $n$ be the total number of trials. The empirical probability of happening of an event E is defined as

$\mathsf{p(e) = \frac{no \: of \: trials \: in \: which \: event \: happened}{total \: number \: of \: trials}}$
