P(E) = 1 - P(not E) 3rd Rule of Probability: Conditional Probability Conditional Probability: The probability of event A AND event B occurring is the probability of event A times the probability of event B, given that A has already occurred. P(A and B) = P(A) × P(B|A) 4th Rule of Probability: Probability of A OR B The probability of event A OR event B occurring is: the probability of event A occurring plus the probability of event B occurring minus the probability of both events occurr...

Round Trip D1 = D2... write out rates equations for both legs of the trip (one will have T and one will have T-X... if there is a stop for lunch and gone for 8 hours, that means only drive for 7 total).... Set equations equal to each other and solve for T! (X / 25) + (x/10) = what percent of X? Find a common denominator and get into one fraction. Xs cancel and the fraction is your answer Takes 1st person c hours to do a job and 2 people together d hours to do the same job. How long will ...
