Sol

Given

Gender self taught in school private total

Female 11 36 27 74

Male 15 26 15 56

Total. 26 62. 42 130

P( musician is female ORsOR is self taught )

P( F OR ST ) = P( F ) + P( ST ) - P( F AND ST )

F= female

ST = self taught

P( F ) = 74 / 130

P( ST ) = 26/130

P ( F AND ST ) = 11/130

P( F OR ST ) = 74/130 + 26/130 - 11/130

= ( 74 +26 - 11 ) / 130

= 89 / 130

= 0.6846153
