If a manufacturing machine gas a 5% defect rate and 9 items are chosen randomly what is the probability that at least one will have a defect ?

Suppose that 20% of all M&Ms are yellow.  We will choose a random sample of 11 M&Ms from this population.  Find the probability that more than 3 of the M&Ms are yellow.  Show work in Excel.

When making random guesses on an 8 question quiz the probability of guessing correctly on any one question is 0.2.  What is the probability of guessing correctly on at least one question?

9. In a large population, 57% of the people have been vaccinated. If 5 people are randomly selected, what is the probability that at least one of them has been vaccinated?Give your answer as a decimal to 4 places.

The number of accidents at a certain intersection is a Poisson random variable. The probability that there are 2 accidents in any given week is 3 times as much as the probability that there are 4 accidents in any given week. Find the probability that there are no accidents at the intersection next week.

An urn contains 10 red balls, 14 green balls, and 7 yellow balls. What is the probability of choosing 2 red balls, 4 green balls, and 3 yellow balls, not necessarily in that order? The balls are chosen without replacement. Your answer should be to 4 decimal places.

A factory produces light bulbs with a 2% defect rate. If a random sample of 100 light bulbs is chosen, what is the probability of finding exactly 3 defective bulbs?

When 2 births are randomly selected, the sample space for genders is bb, bg, gb and gg. Assume that those 4 outcomes are equally likely. Construct a table that describes the sampling distribution of the sample proportion of girls from 2 births. Dies the mean of the sample proportions equal the proportion of girls in 2 births? Does the result suggest that a sample proportion is an unbiased estimator of a population proportion? For the entire population, assume the probability of having a boy is 1/2, the probability of having s girl is 1/2 and this is not affected by how many boys or girls have previously been born. Determine the probabilities of each sample proportion, (type integers or simplified fractions)

A random sample is one on which the
