To add validation rules to a form, you open the form in Layout view and add rules to the properties of individual controls.The steps in the section Add a validation rule to a table explain how to add validation rules to table fields.It's trivial to show that this implies that $P(A\cap B\cap C)=0$.However, if you only know that $P(A\cap B\cap C)=0$ (but not that $A$, $B$ and $C$ are mutually exclusive), it is not necessarily true that $P(A\cap B)=0$. Let $A$ and $B$ be the event that the coin shows heads and $C$ be the event that the coin shows tails. can equal

When data is entered, Access checks to see whether the input breaks a validation rule – if so, the input is not accepted, and Access displays a message.the question I'm trying to solve is saying that A, B and C are all mutually exclusive, no ifs.It doesn't give any other information other than their probabilities and that they're mutually exclusive That answer is above - the first two sentences.This article explains how to use validation rules and validation text in table fields and form controls.A validation rule is one way to restrict input in a table field or a control (such as a text box) on a form.

$; they are sets and sets don't take on numerical values.$ A\cap B \cap C=0$ is incorrect, $P(A\cap B \cap C) = 0$ is not.This can be achieved by a simple check in the form's def clean(self): cleaned_data = super(Test Form, self).clean() if not (bool(self.cleaned_data['test_field1']) !
