A school has 150 students.  110 students take Music and 40 students are left-handed.  There are 32 students who take music and are left handed.  What is the probability that a random student is right handed given they take Music?( person is either right or left handed in this situation)

                           Music              Not Music

Left handed         32                       8                 40

Right handed       78                     32               110

                           110                     40              150

 

P( Right Handed l Taking Music)  =   78/ 110   =    39 / 55   ≈    71%
