need help for question 3.

with using the numbers 21345678

S -> MUV

U -> N| Epsilon

V -> VV|N

N -> M|3|4|5|6|7|8|9|0

M -> 1|2

remove the epsilon

S -> MUV

U -> N

V -> VV|N

N -> M|3|4|5|6|7|8|9|0

M -> 1|2

Consider the following CFG with starting variable S and ={1,2,3,4,5,6,7, 8,9,0} : SMVUNVVVNNM34567890M12 a. [5 marks] Create a derivation tree for your student number. b. [ 5 marks] Is this grammar ambiguous or unambiguous? Briefly explain why. c. [10 marks] Convert the CFG into Chomsky Normal Form
