Answer:

$25\%$

Step-by-step explanation:

$Sample\ Space=Possible\ outcomes\\=\{(1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(2,1),(2,2),(2,3),(2,4),(2,5),(2,6)\\(3,1),(3,2),(3,3),(3,4),(3,5),(3,6),(4,1)(4,2),(4,3),(4,4),(4,5),(4,6)\\(5,1),(5,2),(5,3),(5,4),(5,5),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6)\}\\\\Total\ possible\ outcomes=36\\\\Favourable\ outcomes=9,10\ or\ 11=\\\{(3,6),(4,5),(4,6),(5,4),(5,5),(5,6),(6,3),(6,4),(6,5)\}\\\\Number\ of\ favourable\ outcomes=9$

$Percentage\ chance\ to\ win=\frac{favourable\ outcomes}{total\ outcomes}\times 100\\\\Percentage\ chance\ to\ win=\frac{9}{36}\times 100=\frac{100}{4}\\\\Percentage\ chance\ to\ win=25\%$
