[tex]-10-10+3=-17[/tex]

Therefore, the value of Samanth's cards is -17.

(b)Warren has 7 of club which is a black card so the value of this card is positive 7. The value of 2 of spade is positive 2 and the value of 7 of heart is negative -7.

Therefore, the value of Warren's cards is 2.

(c) The winner name is Warren.
