Question.3589 - Sometimes it helps to visualize the probabilities more easily if you construct a table like the follow: College Degree No Degree Totals Debt 10 53 63 No Debt 25 12 37 35 65 100 By setting up the information this way it may help in seeing what probabilities are being counted twice. So we are looking for P( college degree or no debt) = 35/100 + 37/100 - 25/100 = 47/100The probability of selecting an individual with a college degree (35/100) plus the probability of selecting an individual with no debt (37/100). Now we look and see that we included certain individuals in both probabilities. We can only count them once so we subtract the probability of an individual college degree and no debtTherefore the probability of randomly selecting an individual from this group and they have a college degree or no debt is 47%. Try a couple on you own and see if you can come up with proper conclusions. 1) P(no degree or has debt)2) P(no degree or no debt)3) P(College degree or debt)
Answer Below:
P xx degree xx has xxxx - x no xxxxxx or xx debt x P xxxxxxx degree xx debt x nbspMore Articles From Statistics
