Essay

The accompanying table gives the outcomes and probability distribution of the number of
times a student checks her e-mail daily: $$\begin{array}{l}\text { Probability of Checking E-Mail }\\\begin{array} { | l | l | l | l | l | l | l | l | } \hline \begin{array} { l } \text { Outcome } \\\text { (number of e- } \\\text { mail checks) }\end{array} & 0 & 1 & 2 & 3 & 4 & 5 & 6 \\\hline \begin{array} { l } \text { Probability } \\\text { distribution }\end{array} & 0.05 & 0.15 & 0.30 & 0.25 & 0.15 & 0.08 & 0.02 \\\hline\end{array}\end{array}$$ 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?
