Question

Probability Distribution for Discrete Random Variables

Each semester due to the complexity of Business Statistics 272 at Jefferson State Community College there is a maximum number of students who can enroll as the course is treated more like a seminar.   The maximum number of students is 10.  

Assumption:  Let y represent the number enrolled students and p(y) represent its respective probability.

y	P(y)
0	?
1	0.150
2	0.250
3	0.140
4	0.090
5	0.080
6	0.060
7	0.050
8	0.040
9	0.025
10	0.015

Determine the answer for P(y ≤ 4).  

Determine the answer for P(y ≥ 9).  

Determine the answer for P(3 ≤ y < 7).
