Two books of a student are selected without random substitution where there are four examples of Statistics, three of Mathematics, and two of Finance. If X is the number of books of Statistics and Y is the number of volcanoes of selected Mathematics. construct a table that shows the values of the joint probability distribution of X and Y.

The average number of pages for a simple random sample of 40 physics textbooks is 435. The average number of pages for a simple random sample of 30 mathematics textbooks is 410. Assume that all page length for each types of textbooks is normally distributed. The standard deviation of page length for all physics textbooks is known to be 40, and the standard deviation of page length for all mathematics textbooks is known to be 40. Part One: Assuming that...

15.A box contains five red balls, three green balls, and two yellow balls. Suppose you select one ball at random from the box and do not replace it. Then you randomly select a second ball. Find the probability that both balls selected are red. 16. In a certain region, the probability of flooding in any one year is 1/4.

X P(x) Groups of adults are randomly selected and arranged in groups of three. The random variable x is the number in the group who say that they would feel comfortable in a self-driving vehicle. Determine whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied. Does the table show a probability distribution? Select all that apply. 0...
