Answer 2

Solution:

_____________________________________________________________

Option (a) is wrong,.

first,

By going through the remaining options

(b),

$0\leq P(A) \leq 1$

As we know that probability of a possible event lies between 0 and 1,.

so,it is correct,.

_____________________________________________________________

(c),

P{impossible event} = 0,

We know that,

Probability is the possiblity of an event,

and so, If the event is impossible,.

then it should be 0,.

so,it is correct,.

_____________________________________________________________

(d),

P(S) = 1,.

we know that sample space is the total number of possible outcomes,

so, the probability of an event that occurs as in sample space is 1 (Events can't happen out of sample space.)

so,it is correct,.

⇒∴ (a) is incorrect
