Advice

(a) P({thing[0]})xP({thing[1]})={x}x{y}={a1}

Next round to 2 decimal places to get {a1d}

(b) P(not - {thing[0]})xP(not - {thing[1]}) $=(1-\var{x})\times (1-\var{y})=\var{a2}$

Next round to 2 decimal places to get {a2d}

(d) ( (1-{x})x {y})+( (1-{y})x {x})={a4}

Next round to 2 decimal places to get {a4d}
