A and B are two event such that P(1) = 0.8, P(2) = 0.6 and P(AÇB) = 0.5, then the value of P(A/B) is

A

910\frac { 9 } { 10 }

B

58\frac { 5 } { 8 }

C

56\frac { 5 } { 6 }

D

None of these

Answer

56\frac { 5 } { 6 }

Explanation

Solution

P (AB)\left( \frac { \mathrm { A } } { \mathrm { B } } \right) = 0.50.6\frac { 0.5 } { 0.6 } = 56\frac { 5 } { 6 }
