We elaborate on an alternative representation of conditional probability to the usual tree diagram. We term the representation “turtleback diagram” for its resemblance to the pattern on turtle shells.

The sample space diagram shows there are 6 ways of making a 7, out of a total of 36 possible outcomes. Therefore, the probability of rolling two dice and the sum being 7 is \(\frac{6}{36} = \frac{1}{6 ...
