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)

Look at  the  table :

                           

                        Left Handed           Right  Handed        Total

Music                   32                            78                       110

 

No Music              8                             32                         40

                           __________________________________

                           40                           110                        150

 

P( Right  Handed  given that  they take Music)  =   78 /  110  =    39 / 55
