Question

weight 31-35,36-40,41-45,46-50,51-55,56-60,61-65,66-70 no.of student 9,5,14,3,1,2,2,2, total:38 find the probability that weight of a student in the class lies between 36-45 kg give an event in this context having probability zero

Answer 1

Probability is 1/2---------------

Answer 2

probability = student's weight between 36-45 kg / total number of students
.                = 5+14 / 38
.                = 19 / 38
.                = 1 / 2

The answer is 1 / 2.
