Answer:
a) Answer is : He is mixing up independence and being disjoint .
(b) He is mixing up P(criminal I hoodie ) and P( hoodie I criminal)
(c) She is assuming each card is independent , but there are 52 cards , so they are dependent .
Step-by-step explanation:
a) Answer is : He is mixing up independence and being disjoint .
Note : Deon is thinking the journal says P(AB) = 0 ( which is true for disjoint events not independent events)
(b) He is mixing up P(criminal I hoodie ) and P( hoodie I criminal)
Note : Sebastian finds that is P(hoodie I criminal) is high , that is probability of wearing a hoodie for a criminal is high . But that does not mean P(criminal I hoodie) will also be high , which is the probability that the person is a criminal given that he wears hoodie .
(c) She is assuming each card is independent , but there are 52 cards , so they are dependent .
Note : Probability of one ace is 4/52 . But after first draw number of aces remains 3 and total number of cards remains 51, and after second draw number of aces remains 2 and total number of cards remains 50 and so on
Thus probability of 4 aces is (4/52)*(3/51)*(2/50)*(1/49) = 4c4 /52c4
