# Suppose A and B are independent events. If P(A) = .4 and P(B) = .1, what is P(AnnB)?

Sep 28, 2017

$P \left(A \cap B\right) = 0.04$

#### Explanation:

If events $A$ and $B '$ are independent then:

$P \left(A \cap B\right) = P \left(A\right) P \left(B\right)$

Thus:

$P \left(A \cap B\right) = \left(0.4\right) \left(0.1\right) = 0.04$
