Concept explainers
(a)
To simulate:
The birthday problem for 5 different classes, each with class size of 30 students.
In how many classes does exactly one pair of students share a birthday? In how many classes there are no shared birthdays?
(b)
To simulate:
The birthday problem with 1000 classes.
In what percentage of 1000 classes does exactly one pair of students share birthday?
In what percentage of 1000 classes are there no shared birthdays?
In what percentage of 1000 classes there are more than one pair of shared birthdays?
(c)
To conclude:
Whether the result found in previous parts agree with the probability of shared birthday 0.57 for 25 students.
