## What is the difference between necessity and sufficiency?

## What is the difference between sufficient and necessary causes?

In other words, of one thing is a necessary cause of another, then that means that the outcome can never happen without the cause. However, sometimes the cause occurs without the outcome. If A is sufficient for B (sufficient cause), that means that if you have A, you will ALWAYS have B.

If the hypothesis is true and the conclusion is false, then the conditional statement is false. Likewise, if the hypothesis is false the whole statement is false.

## Can something be sufficient but not necessary?

A sufficient condition is only one of the means to achieve a particular outcome. This means that there could be other means to achieve the outcome. Therefore, a sufficient condition is not necessary to be fulfilled in order to achieve the desired outcome.

## What are the 4 types of conditional sentences?

## What is an example of a conditional statement?
