One in every two times.
A witness.
The frequency of the event over that time period.
biannual
Membership is Not the same as probability.v Probability describes the uncertainty of event occurrence .The probability is an uncertainty associated with time. vFuzziness describes event ambiguity , i.e., the degree to which an event occurs not whether it occurs
Breathing stops for a moment when swallowing. So no breathing occurs when swallowing.
Probability of an event is how many times it occurs.
