Question

A lecture hall has 210210 seats with folding arm tablets, 2929 of which are designed for left-handers. The average size of classes that meet there is 192192, and we can assume that about 1313% of students are left-handed. What's the probability that a right-handed student in one of these classes is forced to use a lefty arm tablet?

Answer #1

A lecture hall has 180 seats with folding arm tablets, 30 of
which are designed for left-handers. The average size of classes
that meet there is 165, and we can assume that about 14% of
students are left-handed. What's the probability that a
right-handed student in one of these classes is forced to use a
lefty arm tablet?

A lecture hall has
200200
seats with folding arm tablets,
1818
of which are designed for left-handers. The typical size of
classes that meet there is
188188,
and we can assume that about
1212%
of students are left-handed. Use a Normal approximation to find
the probability that a right-handed student in one of these
classes is forced to use a lefty arm tablet.
The probability is
nothing.
(Type an integer or decimal rounded to four decimal places as
needed.)

A lecture hall at a university has 220 seats with fold-down
writing pedestals, 30 of which are designed for left-handers. An
Intro. to Economics class with 213 students meets in this lecture
hall. Assume that 13% of the general population is left-handed.
Question 1. What is the probability that at
least one right-handed student in this class is forced to use a
seat designed for a left-hander?
(Use 4 decimal places.)
Question 2. What is the probability that at
least...
