n a classroom there are 100 students, of whom 40 are boys, 30 wear glasses, and 15 are boys who wear glasses. If one student from the class is randomly selected what is the probability that the student will be a girl who does not wear glasses? Independent or dependent
The probability that the student will be a girl who does not wear glasses is dependent on the selection of students in the classroom.
To find the probability, start by finding the number of girls in the classroom.
Girls = Total students - Boys = 100 - 40 = 60
Next, find the number of girls who wear glasses.
Girls wearing glasses = Total students wearing glasses - Boys wearing glasses = 30 - 15 = 15
Now, find the number of girls who do not wear glasses.
Girls not wearing glasses = Total girls - Girls wearing glasses = 60 - 15 = 45
The probability of selecting a girl who does not wear glasses is:
P(Girl and No glasses) = (Girls not wearing glasses) / (Total students) = 45 / 100 = 0.45 or 45%
