Probability and Statistics cheat sheet. F0(x) = f(x) Or alternatively, F x) = Z x 1 f(t)dt Note that by the fundamental theorem of calculus, F (b )a) = Z b a fxdx Thus to nd the probability that a CRV takes on a value in an interval, you can integrate the PDF, thus nding the area under the density curve. Probability is the measure of the likelihood that an event will occur. See glossary of probability and statistics. Probability is quantified as a number between 0 and 1, where, loosely speaking, 0 indicates impossibility and 1 indicates certainty. The higher the probability of an event, the more likely it is that the event will occur. Use poisson for this question. •Problems in probability allow us to draw conclusions about characteristics of
