Triangle JKL on coordinate grid with points J(0,0), K(1,4), L(3,3). Find the coordinates of the vertices of the triangle after a reflection across line x = -1 and then across the x-axis.

a
J'(-2,0), K'(-3, 5), L'(-5,3)
b
J'(2,0), K'(3,-5), L'(5,3)
c
J'(-2,0), K'(-3, -4), L'(-5,-3)

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?
