C. (2) dan (3)

(1) p = Telah bertanding - menang - kalah

= 20 - 15 - 3

= 2

q = (Menang × 5)+(seri × 3)+(kalah × -2)

= (15 × 5) + (2 × 3) + (3 × -2)

= 75 + 6 + (-6)

= 75

Pernyataan (1) Salah karena Faridz mendapat total skor q = 75 poin bukan q = 69 poin

(2) Skor = (Menang × 5)+(seri × 3)+(u × -2)

94 = (17 × 5) + (5 × 3) + -2u

94 = 85 + 15 + -2u

94 = 100 + -2u

2u = 100 - 94

2u = 6

u = 3

t = Menang + seri + kalah

= 17 + 5 + 3

= 25

Pernyataan (2) Benar karena Wildan telah bertanding sebanyak t = 25 kali.

(3) r = Telah bertanding - menang - seri

= 19 - 13 - 4

= 2

s = (Menang × 5)+(seri × 3)+(kalah × -2)

= (13 × 5) + (4 × 3) + (2 × -2)

= 65 + 12 + (-4)

= 73

Pernyataan (3) benar karena Rayyan mendapat total skor s = 73 poin

(4) Pernyataan 4 salah karena Wildan mengalami kekalahan sebanyak u = 3 kali bukan u = 4 kali.
