1. 0 chance (0%)

2. 2 chances (50%)

3. 4 chances (100%)

Explanation:

the way a punnet square works is that you basically multiply two genes. for example:

    b   b

B Bb Bb  

b bb bb  

then, if it's uppercase, it is dominant. if it's dominant, it will take over the recessive gene. if it was Bo, B being brown and dominant, and o being recessive and orange, then brown would take over. there are also cases with codominant but that's not in the question. feel free to ask me anything about this.
