Respuesta :
If half the girls wear glasses, then 8/2 or 4 girls wear glasses.
The whole class is 8+6 or 14 kids.
The probability is the number of girls wearing glasses over the total people in the whole class.
Number of girls wearing glasses/ Total people in class
4/14
Simplify= 2/7
Hope this helps :)

Answer:
[tex]\frac{4}{14}=\frac{2}{7} =28.57%[/tex]
Step-by-step explanation:
In order to calculate a probability we first need to know the total possible outcomes, so the total is boys plus the girls, 6+8=14, we have a total of 14 students, and we need the total number of successfull outcomes, which is half of the girls, 4 girls use glasses.
So the probability is:
[tex]Probability=\frac{Successull outcomes}{Total possible outcomes}[/tex]
[tex]Probability=\frac{4}{14} \\Probability=\frac{2}{7} \\Probability=.2857=28.57%[/tex]
So the probability is 28.57% that if you pick a student at random you will pick a girl with glasses.
