nswer:
cvents A and B are independent because P(A|B) = P(A)
pxplanation:
f aA and B are independent, then:
[tex]P(A\text{ }and\text{ }B)=P(A)\cdot P(B)[/tex]
In this case,
P(A) = 0.4, P(B) = 0.2
If we multiply:
[tex]P(A)\cdot P(B)=0.4\cdot0.2=0.08[/tex]
Which verify what the problem tell us.
Next, the definition of two independent events is P(A|B) = P(A)
