A box contains a large number of pens that are three colours: red, blue and green. The

probability that a pen is faulty depends on its colour. The probability of a faulty red pen is

0.1, while the probability of faulty blue and green pens is 0.15 and 0.08, respectively. In the

box, 35% of the pens is red in colour, 40% is blue in colour and the rest is green in colour.

Identifying Probability Distributions. In Exercises 7–14, determine whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied. Cell Phone Use In a survey, cell phone users were asked which ear they use to hear their cell phone, and the table is based on their responses (based on data from “Hemispheric Dominance and Cell Phone Use,” by Seidman et al., JAMA Otolaryngology—Head & Neck Surgery , Vol. 139, No.
