SOLUTION

GIVEN

E is any event of a random experiment

TO DETERMINE

The probability of the event E belongs to

EVALUATION

In any random experiment if the total number of elementary ( simple) events in the sample space be n ( a finite number) among which the number of elementary events favourable to an event E , connected with the experiment be m then the probability of the event E is denoted by P (E) and defined as

 \displaystyle \sf{}P(E) =  \frac{m}{n}

Now the total number of possible outcomes = n and the total number of possible outcomes for the event E is m

So

 \sf{ 0 \leqslant m \leqslant n\: }

 \implies \displaystyle \sf{ 0 \leqslant  \frac{m}{n}  \leqslant 1}

 \implies \sf{0 \leqslant  \: P(E) \:  \leqslant 1}

 \implies  \sf{P(E)  \in \: [ \: 0, 1 \: ]}

FINAL ANSWER

 \boxed{  \:  \:  \sf{P(E)  \in \: [ \: 0, 1 \: ]} \:  \:  \: }

ADDITIONAL INFORMATION

For an impossible event, the number of favourable cases is zero and hence it's probability is 0

On the other hand for a certain event S all cases are favourable cases and hence it's probability is 1
