If we toss two coins is impossible to get 3 heads (we can get between 0 and 2). So the correct option is D.

Which ones are the possible outcomes?

For two tossed coins, the possible outcomes are:

  • Coin 1,  Coin 2.
  • head    tails
  • head     head
  • tails       tails
  • tails       head.

So there are 4 possible outcomes.

  • in 1, we get 0 heads.
  • in 2, we get 1 head
  • in 1, we get 2 heads.

Then the value of the random variable for the number of heads that is not possible, is the one in option D, 3.

If we toss two coins is impossible to get 3 heads (we can get between 0 and 2).
