Question

A class is made up of 8 boys and 4 girls. Half of the girls wear glasses. A student is selected at random from the class. What is the probability that the student is a girl with glasses.

Answer 1

P(A) = n(A)/n(S)

• P(A) = probability of event A occurring
• n(A) = number of ways event A can occur
• n(S) = total number of possible events

 

For your problem:

      P(selecting a girl with glasses) = n(girls with glasses)/n(total number of students)

      P(selecting a girl with glasses) = 2/12 = 1/6
