    Finding P(Z1|X1Y1) Conditinal Probability..Plz Help..

    Suppose

    X1 Y1 Z1
    0 ..0 ..0 (5 times Z1 is 0 for X1=0 and Y1=0)
    0.. 0.. 0
    0.. 0 ..0
    0.. 0 ..0
    0 ..0 ..0
    0 ..1.. 0
    0 ..1 ..0
    0 ..1.. 0
    0 ..1.. 0
    0 ..1 ..0
    0 ..1 ..0
    0.. 1.. 0
    0 ..1.. 1
    0 ..1.. 1
    0 ..1.. 1
    0 ..1 ..1
    0 ..1.. 1
    0.. 1.. 1
    0 ..1.. 1
    0 ..1.. 1
    .
    .
    .

    Which is..
    (Same table which is above..)

    X1 Y1.......Z1 (Count of Zeros) (Count of Ones)
    0...0 .........................5............2
    0...1 .........................7............8
    1...0 .........................0............10
    1...1 .........................5............1

    I have put Dots since Blanks were disappearing once posted hence what is under which column was difficult to understand..dots dont mean anything..

    Find P(Z1|X1Y1)?

    This makes no more sense to me than the first time you posted it.
