Question: The following table displays a frequency distribution for the number of living grandparents for students at a high school. For a randomly selected student in the school, let X denote the number of living grandparents of the student.
| Number of Living Grandparents | 0 | 1 | 2 | 3 | 4 |
| Frequency | 36 | 72 | 144 | 202 | 155 |
a) Obtain the probability distribution of X.
b) Use the distribution to find the probability that a randomly selected student has at least 1 living grandparent.
c) Find the mean number of living grandparents for these students.
