In OHSAS 18001:2007 it states under clause 3.21 "risk - Combination of the likelihood of an occurrence of a hazardous event ......"
but when i looked up likelihood in Google this came up:
"Likelihood is the hypothetical probability that an event that has already occurred would yield a specific outcome. The concept differs from that of a probability in that a probability refers to the occurrence of future events, while a likelihood refers to past events with known outcomes." on a site called wolfram mathworld
however when we're conducting a risk rating or a risk evaluation whatever you want to call it, likelihood represents the possibility of a specific occurring in the future
Now i'm confused, does it seem right to you, how can likelihood statistically mean that it is the probability of a specific outcome in past events, while in OHSAS18001 it is part of the risk evaluation of future events
can someone please shed some light on this
