If P(E) denotes the probability of an event E then
पर्याय
P(E) < 0
P(E) > 1
0 ≤ P(E) ≤ 1
−1 ≤ P(E) ≤ 1
उत्तर
Since, number of elements in the set of favourable cases is less than or equal to the number of elements in the set of whole number of cases, their ratio always end up being 1 or less than 1.
Also, their ratio can never be negative.
Thus, probability of an event always lies between 0 and 1.
i.e. 0 ≤ P(E) ≤ 1
Hence, the correct answer is option 0 ≤ P(E) ≤ 1.
