Question #122b7

Answer 1

`100%-40% = 60%`

Explanation:

If we are considering the event "It is raining" - there are only two possibilities:

Either: (It IS raining, or it is NOT raining)
The sum of all the probabilities in a given scenario is `100% = 1`

Therefore, if the chance of rain is `40%`,

then the chance of no rain is `100%-40% = 60%`

`P("event does NOT occur") = 1-P("event DOES occur")`
