The results are displayed below in the table. Use this information to answer the following questions. You should input your answers in decimal form, rounded to the nearest thousandth. For example, if you find 0.0148 as an answer, you should enter '0.015". Email 1 Email 2 Email 3 Email 4 Email 5 spam spam spam ham ham buy money nigeria money car profit bank bank home nigeria home check home nigeria profit wire car Part A. Based on the data above, estimate the probability of an arbitrary email being spam, p(spam). Based on the data above, estimate the probability of an arbitrary email being ham, p(ham)- Part B. Given that you know an email is spam, estimate the probability that it contains the word "nigeria". (That is, estimate p(nigeria | spam)) Given that you know an email is ham, estimate the probability that it contains the word "nigeria". (That is, estimate p(nigeria | ham)) Part C. As discussed in class, we can categorize an email by comparing p(ham | email) to p(spam | email), and classifying the given email according to which quantity is larger. In general, these conditional probabilities are estimated using Bayes' Rule as p(category | email) = P(email [ category)p(category) p(email) We note that for both the spam and ham computations, the denominator in this fraction is the same, and thus we can instead classify the email according to which numerator is larger. Compute the estimated numerator for p(spam | nigeria). Compute the estimated numerator for p(ham | nigeria). Part D. Based on your work above, would our spam filter classify an email containing solely the word "nigeria' as ham or spam? Note: Make sure to double-check your answers for Part C before making a selection!Suppuse We llave wie IViewing PIVvauIly distribution: P(x) 0 0.041 1 0.025 2 0.25 3 0.309 4 0.375 Would it be considered unusually low to have a result of x = 1? Read the answers carefully, as they are very similar. ONo, because the probability of obtaining x = 1 is less than 0.05. ONo, because the probability of obtaining x = 1 is more than 0.05. ONo, because the probability of obtaining x = 0 or x = 1 is more than 0.05. OYes, because the probability of obtaining x = 1 is less than 0.05. ONo, because the probability of obtaining x = 0 or x = 1 is less than 0.05. OYes, because the probability of obtaining x = 0 or x = 1 is less than 0.05.WORKSHEET FOR PROBABILITY LAB Instructions: Answer the following questions by writing the appropriate today. answers in the blanks provided.
