Conditional Probability Section 7-4 Name: P(A | B) asks that we find the probability of A given that we know B has or already occurred. Using a formula find the probability of A given B can be found using CONDITIONAL PROBABILITY Determine the following conditional probabilities. Consider a bag with marbles, 3 blue marbles, 2 red marbles, and 5 green marbles. Three marbles are drawn in sequence and are taken without replacement. | | i. = ii. P P(2nd blue red) P(2nd blue blue) draw: 1st draw: draw: 1st draw: = | | iii. P(3rd blue red, blue) = ii. P P(1st blue red) = draw: 1st draw: 2nd draw: draw: 1st draw: Determine the following conditional probabilities. Consider drawing 1 card from a standard deck of shuffled cards: P( Queen | Face Card ) = P( Ace | Lettered Card) = P(number less than 6 | Face Card) = P( Heart with a Number | Red Card) = P( Odd Number | Numbered Card) = P( Card with a Letter| King) = Consider the following with information about all of the students taking Statistics at Phoenix High School. P( Full-time | Male) = P( Female | Part-time) = P( Male | Full-time) = P( Full-time | Part-time) =
