Detailed Solution

  • An impossible event is an event that cannot happen. That means none of the outcomes is favourable. 
  • Receiving an even number when a dice is thrown is not an impossible event as it has a few favourable outcomes - {2, 4, 6}
  • Receiving an odd number when a dice is thrown is also not an impossible event as it has a few favourable outcomes - {1, 3, 5}
  • Receiving a factor of 8 when a dice is thrown is also not an impossible event as it has a few favourable outcomes - {1, 2, 4}
  • Receiving a multiple of 8 when a dice is thrown is an impossible event as none of the outcomes is favourable as multiples of 8 are 8, 16, 24, etc which are always greater than 6.

Therefore, 'Receiving a multiple of 8 when a dice is thrown.' is the correct response.
