Q- Joe will pick 3 friends to join him on a road trip.His friend group consist of 4 musicians and 3 poets.In how many different ways can joe select his 3 traveling companions so that he has atleast one musicians and atleast one poet among them ?
A-Joe has two ways: “two musician and one poet†or “two poet and one musicianâ€.
I’m using slot method.
For the 1st case 4*3*3 =36 and the 2nd case 3*2*4 =24.So,36+24=60 ways ? But the answer is wrong.Where am i going wrong ?
