I have two bags with different color of balls in it. In bag 1 there are 1 white ball and 3 black balls and in bag 2 there are 1 white ball and 2 black balls. I wanna know what is the probability for me getting one black ball and one white ball if I choose one of the bag randomly and grab two balls out from it at once. Hence, what would be the probability for me taking out a black ball and a white ball from the bag 2 instead of bag 1?
my attempt: using binomial to test out the chance but I have gotten some really complicated answer. Would anyone be able to help me with it? Any help would be appreciated
