Need help with constructing DFA and NFA. DFA must have no missing moves or multiple moves.

draw a DFA M₄ that accepts L₄ = {a*bⁿc*: n >= 1}

draw a NFA M₅ that accepts L₅ = {w is an element of {a, b}*: w has an even length and contains the substring bab}

draw a DFA M₆ that accepts L₆ = all binary numbers with an even number of 1's and ending with 101. Leading zeroes are not allowed.
