If two sides of the euqation ARE EQUAL -> independent
NOT equal -> dependent
P(AnB) = P(A) x P(B)

Hi Kevin 💫. For question 4, you said P(A ' n B) is 0, 3.

In your Venn diagram, you cancelled the whole of A circle, forgetting that in between there is the region of (A and B).

So if you cancelled the region of (A and B), you are ignoring the B in that region ? And we are told to find the P(B)?

So my question is... how can we ignore the B in the region of (A and B ). When we are looking for the Probability of B?

I hope you understood my question, and im eager to hear from you soon. 😊

You said " fraction always add up to a total of 1 or 100% " but why on number 2 we just minus with one? Instead of adding and why did we use 1 instead of 100%

So on independant can the question change from and to or so then do we use a different formula

[pumpkineater.]

On question 5 isn't suppose to be P(AnB)' +(PAnB) =1??

Hi kevin, the events are complimentary, they add up to 1

Hey Kevin

Question.1 you said we divide by the total number of the event (as said in the previous video) but you didn’t, why?
