1.3: Measurements, Uncertainty and Significant Figures
The measurement uncertainty has one or two significant figures. We will use just one for the rest of this chapter. The estimate has the same precision as the measurement uncertainty. Suppose you use a digital multimeter to measure the current in a circuit, and the readout is stable (i.e., not fluctuating). Then you should report a result …

Now, I claim that for any p ∈ P, there exists a unique λp such that: λpp + (1 − λp)p ∼ p. (2) Because p o p o p, some such λp exists as a consequence of continuity. The previous step means it is unique. Step 3. Finally, I claim that the utility function U(p) = λp is an expected utility representation of o .
