    The last question had a Venn diagram
    X Y
    (0.3(0.2)0.5)

    Is it exhaustive? Give a reason
    P(X) * P(Y)
    ____
    P(A∪B) = 0.x
    P(A) = 0.y
    P(B) = 0.z

    What does P(A∩B) =?

    Okay so;
    For the comparative pie chart question I got 6.0 (rounded to 1.d.p) because i used the formula r1=r2 x f2square root/f1square root

    For the primary or secondary data question I put primary data since they collect it themselves
    The 60 offices one I put cluster sampling
    the mean of the sunflowers I got 2.79
    The standard deviation I got .709

    I completely messed up on the last page!

    Can everyone else add anything they remember? xx
