This is DFA,

Please, show me the step to create a machine.

assB, u . 1. (25 points) Answer the following questions. (a) (10 points) Prove that A = { x {0, 1}* | #o(x) is even } is regular. (b) (10 points) Prove that B = { x {0,1}* | #1(x) is odd } is regular. (c) (20 points) Prove that C = { x {0,1}* | #o(x) is even and #1(x) is odd } is regular by constructing a product machine from A and B
