Eleven percent of American children (ages 4 to 17) have Attention Deficient Hyperactivity Disorder (ADHD) according to the Center for Disease Control. Suppose six American children in this age group are randomly selected, is the probability that at least one has ADHD unusual? Eleven percent of American children (ages 4 to 17) have Attention Deficient Hyperactivity Disorder (ADHD) according to the Center for Disease Control. Suppose six American children in this age group are randomly selected, is the probability that at least one has ADHD unusual?  No, this probability is not unusual because it is more than 0.05.  Yes, this probability is unusual because it is more than 0.05.  No, this probability is not unusual because it is within 2 standard deviations of the mean.  Yes, this probability is unusual because it is not within 2 standard deviations of the mean.  No, this probability is not unusual because it is more than 0.01.

The survey by the National Center for Health Statistics further found that 49% of adults ages 25–29 had only a cell phone and no landline. We randomly select four 25–29-year-olds: a) What is the probability that all of these adults have a only a cell phone and no landline? b) What is the probability that none of these adults have only a cell phone and no landline? c) What is the probability that at least one of these adults has only a cell phone and no landline?
