Dependent Events (video lessons, examples and solutions)

WebEvents A and B are called mutually exclusive if they cannot both occur, that is, P(A and B) = 0. In this situation, P(A or B) = P(A) + P(B). Events A and B are called independent if the occurrence of one event has no effect on the probability of the other event occurring. In this situation, P(A and B) = P(A)*P(B). Example: suppose two dice are ... WebP(A or B) = P(A) + P(B) − P(A and B) "The probability of A or B equals the probability of A plus the probability of B minus the probability of A and B" Here is the same formula, but using ∪ and ∩: P(A ∪ B) = P(A) + P(B) − P(A ∩ B) A Final Example. 16 people study French, 21 study Spanish and there are 30 altogether.

"WebThe concept of independence applies to any number of events. For example, three events A, B, and C are independent if P (A ∩ B ∩ C) = P (A) · P (B) · P (C). Note carefully that, as is the case with just two events, this is not a formula that is always valid, but holds precisely when the events in question are independent.
