I have been working on this one exercise for a while now and cant really get any further. This is what I have now; WebbProbability is the likelihood or chance of an event occurring. For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail). We write P (heads) = ½ . The probability of something which is certain to happen is 1. list of peacocks stores closingWebbIf the events A and B are not mutually exclusive, then p (A or B) = p (A) + p (B) - p (A and B). The logic behind this formula is that when p (A) and p (B) are added, the occasions on which A and B both occur are counted twice. To adjust for this, p (A and B) is subtracted. im fit products
