Answer:
4% of students tried both questions.
Step-by-step explanation:
Given:
Total students taking the exam = 50
Number of students who answered the first question = 16
Number of students who answered the second question = 33
Number of students who din't answer any = 3
To find the percent of students who tried both questions.
Solution:
Total students who answered at least one question = [tex]50-3 = 47[/tex]
Number of students who tried both questions can be given as :
⇒ [tex]33+16-47[/tex]
⇒ [tex]49-47[/tex]
⇒ [tex]2[/tex]
Percentage of students who tried both questions can be given as:
⇒ [tex]\frac{Number\ of\ students\ trying\ both\ questions}{Total\ number\ of\ students}\times 100[/tex]
⇒ [tex]\frac{2}{50}\times 100[/tex]
⇒ [tex]4\%[/tex]
Thus, 4% of students tried both questions.
