Answer 2

n(A)  = 4 &  p(A) = 1/12

Step-by-step explanation:

In a class of 48 student, 4 students use spectacles

The total number of students in the class is 48

=> n(S)  = 48

Let A be the event that a student uses spectacles

4 students use spectacles

=> n(A)  = 4

p(A)  = Probability that a student selected randomly wearing speactles

p(A) = n(A)/n(S)

=> p(A) = 4/48

=> p(A) = 1/12

n(A)  = 4 &  p(A) = 1/12
