Question
Write the probability of an event when impossible.
✓
Answer
The probability of an impossible event is
Proof : Since E has no element, n(E) =0
from definition of probability :
p(s)=n(E) /n(S)=0/n(s)
p(s)=0
Proof : Since E has no element, n(E) =0
from definition of probability :
p(s)=n(E) /n(S)=0/n(s)
p(s)=0
