Using the Addition Rule. For each of the given pairs of events, decide if the Addition Rule applies. If it does, use the Addition Rule to find the probability that one or the other occurs. You are rolling a standard 6-sided die. Event A A is “roll an even number” and event B B is “roll a 3.”

Single Maths B Probability & Statistics: Exercises & Solutions 1. QUESTION: Describe the sample space and all 16 events for a trial in which two coins are thrown and each shows either a head or a tail. SOLUTION: The sample space is S = {hh, ht, th, tt}. As this has 4 elements there are 24 = 16 subsets, namely
The Addition Law of Probability - General Case If two events are A and B then P(A∪B)=P(A)+P(B)−P(A∩B) Of course if A∩ B = ∅ i.e. A and B are mutually exclusive, then, P(A∩ B)=P(∅)=0and this general expression reduces to the simpler case. This rule can be extended to three or more events, for example:
12 Σεπ 2021 · Let \(\text{X} = \{1, 2, 3, 4, 5\}, \text{Y} = \{4, 5, 6, 7, 8\}\), and \(\text{Z} = \{7, 9\}\). Events X and Y both have 4 and 5. Thus, \(\text{X AND Y} = \{4, 5\}\). Because there are two shared outcomes from the sample space \(S\), the probability of X AND Y is \[P(\text{X AND Y}) = \dfrac{2}{10} \nonumber\] .
