Question

The probability of an event must have what value?

0 < P(E) < 1
P(E) ≥ 0
0 ≤ P(E) ≤ 1
0 < P(E) ≤ 1

Answer 1

`0\leq P(E)\leq 1`

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=(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.
