You can put this solution on YOUR website! Try to break it down into steps. this goes for any *chance* type questions. :)
1. You can count how many letters are in the word "church"
2. then if you want h, count how many "h" are in the word.
3. since there is 2 h, and there are 6 letters, the answer would be:
=
=
this means that there is a one-third chance of "h" being chosen.
Hope this helps!
