Which of the following amongst the given options cannot be the probability of an event:

(i) 1.01 (ii) 67%


(iii) -0.5 (iv)


(v) 0.3

we know that 0<P(Event)<1.


we know that the probability of any event varies between 0 to 1 and cannot be negative.


(i) greater than 1 so it cannot be possible.


(ii) Since 67% = = 0.67 possible


(iii) it cannot be negative.


(iv) It is within the range, so possible
