Find parametric equations of the image of pq under the transformation l
xy
= a
xy
for the given points p, q,
and matrix a.
a. p(2,1), q(−1, −1), a = 3
1 2

b. p(0,0), q(4,2), a = 1 2
−2 1

c. p(3,1), q(1, −2), a = 4
0 1

Simplify (1/2)4th power a. (1/16) b.(1/8) c.(1/4)

There are three bags: a (contains 2 white and 4 red balls), b (8 white, 4 red) and c (1 white 3 red). you select one ball at random from each bag, observe that exactly two are white, but forget which ball came from which bag. what is the probability that you selected a white ball from bag a?
