Question

I need help with this pls

Answer 1

nswer:

cvents A and B are independent because P(A|B) = P(A)

pxplanation:

f aA and B are independent, then:

`P(A\text{ }and\text{ }B)=P(A)\cdot P(B)`

In this case,

P(A) = 0.4, P(B) = 0.2

If we multiply:

`P(A)\cdot P(B)=0.4\cdot0.2=0.08`

Which verify what the problem tell us.

Next, the definition of two independent events is P(A|B) = P(A)
