Answer 1

The probability of getting ladies who likes coffee=36÷100=9÷25
The probability of getting the ladies who dislikes coffee=64÷100=16÷25
the one who likes coffee=
$\frac{9}{25}$

the one who dislikes coffee=
$\frac{16}{25}$

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

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