Here is another question I find difficult to comprehend for me... If Pr(A)=0.7, Pr (A Intersection B)=0.32 and the Pr(A` Intersection B`)=0.10, then the Pr (B)= I know the formula Pr(A Union B)=Pr(A)+Pr(B)-Pr(A Intersection B) but don't know what the dashes mean and how to work out Pr(B)

Hi there this question really stumped me... A die is rolled three time. The probablity of getting at least one odd number is what? A tree diagram would be too long to do and the lattice might be useful, other than that I have no clue on how to do it. Thanks

Thanks to who ever can help me with my homework. Assume the normal model and find the following z scores? 1. the value of z cuts off the highest 15% 2. the value of z cuts off the highest 89% 3. the value of z cuts off the lowest 9% 4. the value of z cuts off the middle 54% Find the...

Two cards are drawn from a standard deck of 52 cards. Find the probablity of both cards either red or a king.

A card is selected at random from a standard deck of cards.Determine each probablity. P(5), P(red 10) , P(odd Number) , P(queen of hearts or jack of diamonds). :confused: :confused: :confused:
