Question

Probability of an impossible event is

• A. 1
• B. -1
• C. 0
• D. 2

Answer 1

The correct option is C 0

Consider the given event,

Probability of possible event is $=1$

And probability of impossible event is $=\varphi or0$

Probability exists on a scale from $0\text{to}1$, with $0$ being defined as impossible and $1$being defined as certain.

Everything between $0\text{and}1$ is possible, and with increasing probability, events become more likely.
