F(x) = |5x + 1| - 3 g(x) = 4
find (f - g)(x)
A. (f - g)(x) = |5x + 1| - 7
B.(f - g)(x) = |5x| - 6
C.(f - g)(x) = |5x - 2| - 4
D.(f - g)(x) = |5x - 6|

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?
