Answer:

-0.075

Step-by-step explanation:

[Player R, Player C] cases & outcomes :-

  • (Vowel, Vowel) = (0,0)
  • (Consonant, Consonant) = (0,0)
  • (Vowel, Consonant) = (6,-6)
  • (Consonant, Vowel) = (-5,5)
  • Prob (R chooses consonant) = 75% = 0.75
  • Prob (R chooses vowel) = 1 - 0.75 = 0.25
  • Prob (C chooses vowel) = 30% = 0.30
  • Prob (C chooses consonant) = 1 - 0.30 = 0.70

Average Loss of R = Expected value of : he choses consonant & C choses vowel; he chooses vowel & C choses consonant

= (0.75)(0.30)(-5) + (0.25)(0.70)(6)

-1.125 + 1.05

= -0.075
