To decide who should go out and buy matches to light the candles with, one decide to throw two dice and guess the outcome. Lea exchange the one die for her special die.

1. what is the probability of hitting 9 points with this set of dice, and is it more or less than with normal dice?

2. Rakel actually knew about Lea's special die, and has obtained a similar one, with the one having the highest chance and the six having the lowest. She replaces the normal die with this one. will the probability of hitting 9 now become normal?

3. does the same apply to double-six?
