The weatherman might state that your area has a probability of rain of 40 percent. However, this fact is conditional on many things, such as the probability of…
  • …a cold front coming to your area.
  • …rain clouds forming.
  • …another front pushing the rain clouds away.
We say that the conditional probability of rain occurring depends on all the above events.
