probability that question will solved = at least one student solve the question
= 1/3*1/4*1/5+1/3*1/4*4/5+1/3*3/4*1/5+2/3*1/4*1/5+2/3*3/4*1/5+2/3*1/4*4/5+1/3*3/4*4/5
= (1+4+3+2+6+8+12)/60
= 36/60
= 3/5 or 0.6
= 1/3*1/4*1/5+1/3*1/4*4/5+1/3*3/4*1/5+2/3*1/4*1/5+2/3*3/4*1/5+2/3*1/4*4/5+1/3*3/4*4/5
= (1+4+3+2+6+8+12)/60
= 36/60
= 3/5 or 0.6
