Let E and F be events such that the following is true.
Pr (E) = 0.26, Pr (F ' ) = 0.61, Pr (E F) = 0.61
What is Pr (E ∩ F)?

    Pr (E) = 0.26, Pr (F ' ) = 0.61, Pr (E∪F) = 0.61.
    What is Pr (E ∩ F)?

    Hint: use
    P(F)=1-P(F')
    P(E∪F)=P(E)+P(F)-P(E∩F)

  • math-Probability -

    Pr(EnF)= .04
