Question

which one of the following cannot be the probability of an event

(A)2/3
(B)-1.5
(C)15%
(D)0.7​

Answer 1

Step-by-step explanation:

As we know the probability of any event lies between 0 and 1. It can never be negative nor greater than 1. Hence, -1.5 is negative. ∴ Option b cannot be a probability of an event.

Answer 2

Step-by-step explanation:

let probability of given event be 'p'

0≤p≤1

This is the condition

now,

A)2/3 =0.67 _satisfies

B)-1.5 _doesn't satisfy because it is less than zero

C)15% = 15/100=0.15 _satisfies

D)0.7 _satisfies
