Lorne rolls two regular six-sided dice. Determine the odds against him rolling an odd sum or a 4

A couple has eight children. Suppose that the probability of having a girl is 0.5. What is the probability of producing eight girls? How does that answer compare with the probability of producing boy, girl, boy, girl, boy, girl, boy, girl? Explain.

Flip three fair coins. Let the number of heads be the number of dice we roll. If the numbers on the upper faces of the dice add up to 5, what is the probability that two heads turned up?

Find the probability for a roll of two dice. Rolling a sum of 8 (the sum is found by adding the 2 faces of the dice). (Round your answer to 3 decimal places)

A bag contains 2 gold marbles, 10 silver marbles, and 26 black marbles. You randomly select one marble from the bag. What is the probability that you select a gold marble? Write your answer as a reduced fraction.PP(gold marble) =

Arsenic is a compound that occurs naturally in very low concentrations. Arsenic blood concentrations in healthy individuals are Normally distributed with a mean of 3.2 mg/dl. Some areas of the United States have naturally elevated arsenic levels in the ground and water supplies. Researchers took a sample 20 water samples from a particular area and measured the arsenic levels in each of the 20 water samples. They want to determine if there is sufficient evidence to conclude that the arsenic level in that area is higher than 3.2 mg/dl. hypothesis test for one population mean (unknown population standard deviation) confidence interval estimate for one population mean (unknown population standard deviation) hypothesis test for population mean from paired differences confidence interval estimate for population mean from paired differences hypothesis test for difference in population means from two independent samples confidence interval estimate for difference in population means from two…
