Number of students 21-25: 402
Number of students 26-30: 210
Number of students 31-35: 55
Number of students over 35: 24
Total number of students: 1107
A student from the community college is selected at random. Find the probability that the student is between 26 and 35 inclusive. Round approximations to three decimal places.
Probability of age 26-35 = 0.239 or 23.9 %
Step-by-step explanation:
The no. of students in the age 26-35 = no. of students of age 26-30 + no. of students of age 31-35
The no. of students in the age 26-35 = 210 + 55
The no. of students in the age 26-35 = 265
Total no. of students: 1107
Probability of age 26-35 = The no. of students in the age 26-35/ Total no. of students
Probability of age 26-35 = 265/1107
Probability of age 26-35 = 0.239
Probability of age 26-35 = 23.9 %
