The ratio of atoms is 2:4:2. Dividing by the lowest common denominator (2) gives the simplest, whole-number ratio of atoms, 1:2:1, so the empirical formula is CH 2 O. Note that a molecular formula is always a whole-number multiple of an empirical formula. Figure 6. (a) Vinegar contains acetic acid, C 2 H 4 O 2, which has an empirical formula of ... Consider three urns, one colored red, one white, and one blue. The red urn contains 1 red ball, 1 white ball, and 2 blue balls; the white urn contains 2 white balls and 1 blue ball; the blue urn contains 3 white balls and 1 blue ball. At the initial stage (n = 0), a ball is randomly selected from the red urn and then returned to that urn. Three balls are drawn without replacement from the urn, and the colors are noted in sequence.

Solution: Determine the probability that red or white is drawn at random. Solution: What is the probability of getting 6 right of pure guesswork?What we assume: Lacking any prior knowledge we must give equal weighting to the possibilities that the bag contains 2, 3, or 4 white balls. Thus we assign the prior probabilities as: $\mathsf P(A)=\mathsf P(B)=\mathsf P(C)=\frac 1 3$. This is pretty much just guestimation; but we must start somewhere.
