... We also know that P_j = P_b - 0.2 and P_m = P_b - 0.2. Substituting these into the previous equation gives 3 P_b - 0.4 =1 and therefore P_b = 1.4/3 = 14/30 which gives the approximate value of 0.467 for Barbara's probability of being hired. 20. The coefficients of the quadratic equation x^2 + b x + ...

Probabilistic Reasoning
... Discrete Probability • If a discrete RV X has values v1,…vn, then a prob distribution for X is non-negative real valued function p such that: sum p(vi) = 1. • Prob(fair coin comes up heads 0,1,..10 in 10 tosses) • In math, pretend p is known. Via statistics we try to estimate it. • Assigning RV is ...

... the number of times the outcome occurs divided by the total number of trials of the experiment. The relative frequency of an event is the number of times the event occurs divided by the number of trials the experiment was performed. • Uniform distribution: Recall that a probability P is a function w ...
