Sleep Disorders A survey finds that \( 18 \% \) of Americans suffer from a sleep disorder. For a randomly selected sample of 15 people, find each probability. Round intermediate calculations and final answers to at least three decimal places. Part 1 of 3 (a) At least 3 people have a sleep disorder \[ P(\text { at least } 3 \text { people have a sleep disorder })=0.523 \] Part: 1 / 3 Part 2 of 3 (b) 2 or 3 people have a sleep disorder \( P(2 \) or 3 people have a sleep disorder \( )= \) \( \square \)

A survey finds that 23% of Americans suffer from a sleep disorder. For a randomly selected sample of 25 people, find the probability that exactly 1 person has a sleep disorder. Round intermediate calculations and final answers to at least three decimal places.

The table gives the results of a 2008 survey of Americans aged $18-24$ in which the respondents were asked, "During the past 30 days, for about how many days have you felt that you did not get enough sleep?"$$\begin{array}{|l|c|c|c|c|}\hline \text { Number of Days } & 0 & 1-13 & 14-29 & 30 \\ \hline \text { Percent (as a decimal) } & 0.23 & 0.45 & 0.20 & 0.12 \\\hline\end{array}$$ Using the percents as probabilities, find the probability that, out of 10 respondents in the $18-24$ age group selected at random, the following were true. Exactly 4 did not get enough sleep on $1-13$ days.
