The Accompanying Table Gives the Outcomes and Probability Distribution of the Number

Essay

The accompanying table gives the outcomes and probability distribution of the number of times a student checks her e-mail daily:
Probability of Checking E-Mail $$\begin{array} { | l | l | l | l | l | l | l | l | } \hline\begin{array} { l } \text { Outcome } \\\text { number of e- } \\\text { mail checks) }\end{array} &0 & 1 & 2& 3 & 4 & 5 & 6 \\\hline \begin{array} { l } \text { Probability } \\\text { distribution }\end{array} & 0.05 & 0.15 & 0.30 & 0.25 & 0.15 & 0.08 & 0.02 \\\hline\end{array}$$ Sketch the probability distribution. Next, calculate the c.d.f. for the above table. What is the probability of her checking her e-mail between 1 and 3 times a day? Of checking it more than 3 times a day?
