Hello, I am working on a homework, and so far this is what I got. Could anyone please help if I get this correct and if not, what mistake did I make and how to fix it? Thank you in advance Categorize the following languages:

a)B = {w| w has at least three as and at least two bs}, assume ={a, b}.

b)B = {ww | w{0, 1}*}.

c)B = {ww^R | w{0, 1}*}.

d)B = {aⁿbⁿ | n>=0}.

e)B = {aⁿbⁿcⁿ | n 0}.
