The heights of women in the USA are normally distributed with a population mean of 64.5 inches and a population standard of 2.5 inches. What is the probability that a woman randomly selected from the population will be taller than 65 inches?

The pre-cooked weight of hamburgers at Krusty Burger is normally distributed with a population mean of 5.5 ounces and standard deviation of 0.15 ounces. If you walk into Krusty Burger and order a burger, what is the probability that the pre-cooked weight of the burger you just ordered is less than 5.3 ounces?

A survey of hotel guests in Alabama found that 20% of all guests were highly satisfied with their stay. If we take a random sample of 15 guests, what is the probability that at least 10 of the 15 will say they were highly satisfied? 

Given that x is a hypergeometric random variable with population size (N) = 10, sample size (n) = 5, and number of successes in the population (s) = 7, find P(X=3).

If a standard, six-sided die is tossed three times, the probability of obtaining three “6s” in a row is:

In a continuous probability distribution, the probability that any random variable will take on an exact value:
