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?
