I need the exam to show the steps to how the answer was achieved

1-6
    P(T)=70%
    P(S) = 60%
    P(T and S) = 40%
    1)    FALSE
        Disjoint events cannot happen at the same time. there are 40% chances that both like thottela chips and Salsa. I can say that the given statement is false.
    2)    C. (x=.2, y=.4, z=.3)
        x=(.60-.40 = .20), y=.4, z=(.7-.40 = .3)
    3)    D. 20%
        60%-40% = 20%
    4)    A. 90%
        P(T or S) = P(T)+P(S)-P(TS) = 60%+70%-40% = 90%
    5)    P(T|S)     =P(T and S)/P(S)
             =40%/60%
            66.67%
        A. 66.7%
    6)    events are independent if P(A)*P(B) = P(AB)
        Here, P(T)*(P(S)=    42.00%
        And P(TS) =    40%
        Since P(T)*P(S) =/= P(TS), events are not independent
        B. No
