A-Level Maths: M1-03 [Probability: Finding Probabilities from a Venn Diagram]

[melissacartaya]

You made this easy, somehow. I have literally shed tears today trying to figure this out. I was turned away by tutors at my university because my math class wasn't "advanced" enough for them to help me. Thank you, kind stranger, for helping me. I'm so thankful for the helpers of the world like you.

thanks for the funny shapes mr. maths man, you don't realize how much of a visual learner you are until you are

[Doodo]

I’m still a bit confused on the last one, could you try and explain it in a different way

If a question ask you to write down a mutaully exclusive pair, from a ven diagram how would you write it?

[tofjackn]

If you had two venn diagrams and you were told neither A or B is 0.1. Which sections of the venn diagram would it be? Also whats would the notation be... would it be P(A'uB')

[H-ho]

Why do you add up the total surely for the first one it would just be 2/4

[sarahalawadh]

for question g why didn't you add 4 to eight because it said A' so shouldn't we add the 4, a bit confused

[JJFHNREHJEDK]

I thought P(AuB) = P(A) + P(B) - P(AnB)
So for part e why woudn't it be (15+8-3)/30 ?

[XedElectrix]

What if it was P(AuB') or vice versa?
