Solution

Total number of outcomes when 3 dice are thrown = `6xx6xx6=216`

Number of outcomes in which there is an odd number on all the three dice =`3xx3xx3=27`

∴ Number of outcomes in which there is an even number at least on one dice = {Total possible outcomes}-  {Number of outcomes in which there is an odd number on all the three dice } =`216xx27=189`

  Is there an error in this question or solution?
