To calculate:The probability that a randomly chosen student attended at most 10 events
a.
Answer to Problem 5PPS
Theprobability for a randomly chosen student attended at most 10 events is
Explanation of Solution
Given information:
Number of student wanted to participate in 0 to 5 events is 96
Number of student wanted to participate in 6 to 10 events is 112
Number of student wanted to participate in 11 to 15 events is 204
Number of student wanted to participate in 16 to 20 events is 108
Number of student wanted to participate in more than 20 events is 80
Calculation:
The probability for a randomly chosen student attended at most 10 events can be calculated when the number of student participated in 10 or less events is divisible by total number of students.
Therefore, the probability for a randomly chosen student attended at most 10 events is
b.
To calculate: The probability that a randomly chosen student attended at least 16 events
b.
Answer to Problem 5PPS
The probability for randomly chosen student attended at least 16 events is
Explanation of Solution
Given information:
Number of student wanted to participate in 0 to 5 events is 96
Number of student wanted to participate in 6 to 10 events is 112
Number of student wanted to participate in 11 to 15 events is 204
Number of student wanted to participate in 16 to 20 events is 108
Number of student wanted to participate in more than 20 events is 80
Calculation:
The probability for randomly chosen student attended at least 16 events is calculated when number of students participated in 16 or more events is divisible by total number of students
Therefore, the probability for randomly chosen student attended at least 16 events is
