Urn A contains four white balls and three black balls. Urn B contains six white balls and seven black balls. A ball is drawn from Urn A and then transferred to Urn B. A ball is then drawn from Urn B. What is the probability that the transferred ball was white given that the second ball drawn was white? (Round your answer to three decimal places.) I can't seem to figure this out! Please help! Thank you!

Three positive integers (a, b, c) with a<b<c are called a Pythagorean triple if the sum of the square of a and the square of b is equal to the square of c. Write a program that prints all Pythagorean triples (one in a line) with a, b, and c all smaller than 1000, as well the total number of such triples in the end. Arrays are not allowed to appear in your code. Hint: user nested loops (Can you...
