    Answer:

    1   3/5*2/3=6/15

    2   (3/5*2/3)+(2/3*5/6)+(3/5*5/6)=Ans

    3  same as 2 i think

    4  3/5+2/3+5/6=ans

    5 (1-3/5)*(1-2/3)*(1-5/6)

    Explanation

    1 means x and y… for such a  we multiply the probabilities

    2 means x and y or x and z or y and z9 multiply ands  add ors

    3 i think it is same as 2

    4 for this you have to negate the probabilities of killing to find that of not killing.   Since it will be x and y and z, you multiply the final probabilities
