WebThis is the intersection of events A and B; that is, we want to know P (A ∩ B). Next, we specify the known probabilities: P (A) = 0.5, since Mary gives up a home run half the time. P (B) = 0.75, since Mary wins 75% of the time. P ( B A ) = 0.5, since Mary wins only half the time when she gives up a home run. WebContinuous probability distributions are given in the form. whereby the above means that the probability density function f(x) exists within the region {x;a,b} but takes on the value of zero anywhere else.
