Two balls are randomly drawn from bowl that contains six white and five black balls.
00:05
What is the probability that one of the drawn balls is white and the other is black? two balls are randomly drawn.
00:12
So if one ball is drawn, so this has six white and five black balls.
00:21
When the first ball is drawn, it can be a white or it can be because we need white and the first, then one of the ball is white and the other one is black.
00:30
So they are not interested in the order.
00:33
So might be the first one is white and the next one is black.
00:36
Or since it's an order i'm adding it, and since it's a product rule over here, we need both.
00:42
So i'm multiplying it.
00:43
Or the first one is black and the second one is white.
00:46
So what is the probability of having a white ball? so favorable number of white balls are six...
