1. The problem statement, all variables and given/known data 45% of emails sent to my account is spam. i set up a filter but it fails toquarantine 2% of spam and in advertently quarantines5% of genuine emails. What is the probability that an email will be quarantined as spam? if an email is qurantined as spam what is the probability that is actually spam? 2. Relevant equations 3. The attempt at a solution so i take it that this isconditional probabability so the im looking at P(alb) = P(a[itex]\cap[/itex]b) / P(b) but im not sure as to what to use as a and b B is going to be the probability of it being spam in the first place which will be .45 as it misses 2% of spam and included 5% of genuine emails. so is a 0.45 - 0.009 + 0.011 ?
