5. On the first line of the table, enter the value for P(X ≤ 0) that you found in question#4(. On the second line, enter the value for P(X ≤ 1)(Number 4 reffered to the table only divided into two.) Continue filling in the whole table. You may notice a shortcut as you go... 6. What is the last entry? Why does this make sense? 7. We use the shorthand F(x) to mean P(X ≤ x), and we call F(x) the Cumulative Probability Distribution for our random variable X. Why do you think we call it that?

5. On the first line of the table, enter the value for P(X ≤ 0) that you found in question#4(. On the second line,
enter the value for P(X ≤ 1)(Number 4 reffered to the table only divided into two.) Continue filling in the whole table. You may notice a shortcut as you
go...

7. We use the shorthand F(x) to mean P(X ≤ x), and we call F(x) the Cumulative Probability Distribution
for our random variable X. Why do you think we call it that?
