WebExamples and Solutions. Some illustrations will improve the understanding of the concept. Example 1: A bag I contains 4 white and 6 black balls while another Bag II contains 4 white and 3 black balls. One ball is drawn at random from one of the bags, and it is found to be black. Find the probability that it was drawn from Bag I. Solution: WebJul 16, 2024 · The probability that one marble is red and the other white. Solution. Let \(\mathrm{R}\) be the event that the marble drawn is red, and let W be the event that the marble drawn is white. We draw the following tree diagram. The probability that both marbles are red is \(\mathrm{P}(\mathrm{RR})=6/42\)
