The company Corp manufactures plastic balls, bags, and jacket
for kids
The production of these three products requires plastic. The
production process uses two types of skilled labor: sewing and
finishing. The table below shows the consumption of manufacturing
resources per unit produced.

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!

There are three assets A, B and C. The returns for shares A, B
and C over the next year have expected values 9%, 6%, 5%
respectively. The standard deviations for A, B and C are 30%, 25%
and 20% respectively. The covariance between these A and B is
0.0375, the covariance between A and C is -0.018, the covariance
between B and C is -0.03. Ben currently has invested 40%, 40%, 20%
in shares A, B and C respectively....

A box contains three white balls, two black balls, and one red
ball. Three balls are drawn at random without replacement. Let Y1
be the number of white balls drawn, and Y2 the number of black
balls drawn. Find the distribution of Z = Y1 × Y2

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.

A bag contains 4 red balls and 8 green balls.
(a). (5’) Three balls are selected from the bag randomly. What
is the probability that 1 red ball and 2 green balls are
selected?

without replacement, and the first ball is discarded without
observing the color. If the third ball is green, what is the
probability that the second ball is red?
(c). (10’) Two balls are selected from the...
