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.
Event A is the probability of town A voting for Steve, and Event B is the probability of town B voting for Steve. To find the probability of both of these events happening, you can use the Multiplication Rule of Probability by simply multiplying the two probabilities like this: 1/4 * 5/7 = 5/28 or approximately 18%.he Multiplication Rule of Probability is used to find the intersection of two different sets of events, called independent and dependent events. Independent events are when the probability of an event is not affected by a previous event.
