How to set up a probability problem
Web"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. Work out the probabilities! WebFigure out how many standard deviations away from the mean your proportion is, then consult a z-table and figure out the values. In other words, since the mean is 0.15 and we want to figure out what the probability that it's greater than 0.10, then the distance from our proportion to the mean is 0.05.
