In a certain population, one out of 25 people are color blind, on average.
(a) If a random sample of 30 people is chosen, what is the probability that there is at least one color blind person?
Hint: Find the probability that none of the 30 people is color blind.
(b) Use the inclusion-exclusion formula to find the probability that in a random sample of two people (i.e., the people are independently chosen), at least one of the two is color blind.
(c) Use the inclusion-exclusion formula to find the probability that in a random sample of three people, at least one of the three is color blind.

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...

You are a member of a population of 10,000 people. You happen to be chosen for a simple random sample of size 1,000 this year. Then you are chosen for another simple random sample of size 100 (drawn independently of the first sample) next year. You think you're incredibly unlucky to be chosen for two such samples, but how unlucky are you? The probability of this happening is which of the following? a. (1/10,000)2 b. 2/10,000 c. 1/10 d. 1/1,000

One percent of all individuals in a certain population are carriers of a particular disease. A diagnostic test for this disease has a 95% detection rate for carriers and a 4% detection rate for non-carriers. Suppose the test for this is applied independently to two different blood samples from the same randomly selected individual. Hint: Use Notation A= {no disease} A'={disease} B1= {1st test positive} B2={2nd test positive} a) What is the probability that the first test is positive? b)...
