In a random sample of 64 people it was found that 42 of them could name all fifty states in the U.S. If two people from this sample are randomly chosen without replacement, what is the probability at least one of these two people can name all fifty states?
Round your answer to 4 decimal places.
(Hint: The complement of "at least one" is "none". Find the
probability that neither of the two people chosen can name all
fifty states and then use the "complements principle" to find your
answer.)
please show all steps on how to figure this out.
Homework Answers
Number of people who can't name all fifty states = 64 - 42 = 22
Hence,
P(At least one of these two people can name all fifty states)
= 1 - P(None of these two people can name all fifty states)
= 1 - (22/64)*(21/63)
= 0.8854

OD Suppose that 12% of the population of the U.S. is left-handed. If a random sample of 130 people from the U.S. is chosen, approximate the probability that at most 14 are left-handed. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps. (If necessary, consult a list of formulas.)

1. Walgreens sells both Kleenex and NyQuil. In a random sample of 5000 purchases, it was found that 1200 contained Kleenex and 540 contained NyQuil. These are not independent because sick people are more likely to buy both and healthy people more likely to buy neither. In looking into that, it was found that 360 purchases contained both. a.
