Each
suppose you want to simulate surveying 100 people to find the date of the month (1st, 2nd, 3rd
simulation provide a fair representation of an actual survey of 100 people? why or why not?
yes, because all possible dates of the month would be represented.
no, because for the 12 months in the year each date is not equally likely.
no, because for the 12 months in the year not all of the dates are represented.
yes, because it is possible to get 100 random values in a simulation.

In proof testing of circuit boards, the probability that any particular diode will fail is 0.01. suppose a circuit board contains 200 diodes. (a) how many diodes would you expect to fail? what is the standard deviation of the number that are expected to fail? (round your answer to three decimal places.) (b) what is the (approximate) probability that at least six diodes will fail on a randomly selected board? (round your answer to three decimal places.) (c) if five boards are shipped to a particular customer, how likely is it that at least four of them will work properly? (a board works properly only if all its diodes work. round your answer to four decimal places.)
