Răspuns :
Map = 2/5*3 + 3/4*2 totul supra 3+2
Map = 6/5+3/2 totul supra 5
Map = 12/10+15/10 totul supra 5
Map = 27/10 :5
Map = 27/10*1/5
Map = 27/50
Map = 6/5+3/2 totul supra 5
Map = 12/10+15/10 totul supra 5
Map = 27/10 :5
Map = 27/10*1/5
Map = 27/50
((2/5)×3+(3/4)×2)/(3+2)=(6/15+6/8)/5=(2/5+3/4)/5=(8/20+15/20)/5=23/20:5=23/100=0,23
