Probability Cause and Effect Problem
Question What does it mean for one event ? to cause another event ? – for example, smoking (?) to cause cancer…
Probability Problem: Suppose you roll a fair die two times. Let ? be the event “THE SUM OF THE THROWS EQUALS 5” and ? be the event “AT LEAST ONE OF THE THROWS IS A 4”. Solve for the probability that the sum of the throws equals 5, given that at least one of the throws is a 4. That is, solve ?(?|?).
Solution We have A = (1,4), (2,3), (3,2), (4,1) B = (1,4), (2,4), (3,4), (4,4), (5,4), (6,4), (4,1), (4,2), (4,3), (4,5), (4,6)…
