Question

The probability of an event must have what value?

Answer 1

Answer:

$0\leq P(E)\leq 1$    

Step-by-step explanation:

Probability is the occurrence of any event it lies between 0 and 1

If there is 100 % chance to occur any event then probability is 1 and if there is no chance to occur any event then probability is 0

Probability is given by $P=\frac{favorable\ outcomes}{total\ otcomes}$

As the total outcomes is always greater than favorable outcomes so probability will be always less than 1 and it can't be negative so greater than zero.
