b
Step-by-step explanation:
From the question we are told that
The number of players in Taft High School is t = 8
The number of players in McKinley High School is k = 7
The number of rounds is n = 4
The highest number of match each player can play is w = 1
Generally the total number of schedules is


=> 
=> 
=> 
=> 
Generally the number of schedules that include neither of the sisters is mathematically represented as


=> 
=> 
=> 
=> 
=>
Total number of questions = 50
Number of questions answered incorrectly = 5
Therefore,
Number of questions answered correctly = 50-5 = 45 questions
Now, to get the percentage of correct answers, we will divide the number of correct answers by the total number of questions and then multiply the quotient by 100 as follows:
% of correct answers = (45/50) * 100 = 90%
Comparing the calculated value to the choices we have, we will find that the correct choice is:
D. 90%
