Answer 1

it is impossible to get an even number by adding three odd numbers. so, odd + odd + odd =/= 30 hence it is an impossible event It is possible only in case of factorial. 3! + 15 + 9 = 30 3! + 11 + 13 = 30 3! Refers 3x2x1 = 6 In odd number it can be represent as 3!

Answer 2

 the answer can be: 7 + ( 1+ 9 ) + 13 = 30 because there is no rule that we cannot use brackets
