Fish with Mercury: Fish that contain high levels of mercury should be avoided. Mercury consumed during pregnancy has been linked to developmental delays and brain damage. A sample of these types of fish includes: shark, swordfish, king mackerel, and tilefish.
We need a rule to guide us. Addition Rule 1: When two events, A and B, are mutually exclusive, the probability that A or B will occur is the sum of the probability of each event. P(A or B) = P(A) + P(B) Let's use this addition rule to find the probability for Experiment 1.
(35.5) tells how the probability for the theory must bemodiï¬ed in the light of the new data to give the posterior probability, P(theory|data). AsEq. (35.5) is stated as a proportionality, the probability must be normalized by summing(or integrating) over all possible hypotheses. 35.2. Random variables A random variable is a numerical characteristic assigned to an element of the samplespace. In the frequency interpretation of probability, it corresponds to an outcome ofa repeatable experiment. Let x be a possible outcome of an observation.
