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.
MAIN CONCEPTS. Probability is a name assigned to the relative frequency of an event in an event space, that is, a set of possible events. For example, we might define the event space as the two sides of a single coin labeled heads (H) and tails (T): {T, H}.
