In Hawaii shark attacks are very rare. Furthermore, about 55% of all shark attacks are serious, but not fatal. You are scheduled to give a talk at a local scuba club in Honolulu and want to include a brief statistical profile regarding the most recent eight shark attacks, all of which were nonfatal. Let r be the number of nonfatal attacks out of a random sample of eight shark attacks. So, what is the probability that five or more of the eight shark attacks are nonfatal?

I personally have used statistics in trying to challenge the reliability of drug testing results. Suppose the chance of a mistake in the taking and processing of a urine sample for a drug test is just 1 in 100. And your client has a "dirty" (i.e., positive) test result. Only a 1 in 100 chance that it could be wrong? Not necessarily. If the vast majority of all tests given-say 99 in 100-are truly clean, then you get one false dirty and one true dirty in every 100 tests, so that half of the dirty tests are false. Define the following events as: TD = TC = D = event that the person tested is actually dirty C = event that the person tested is actually clean (a) Using the information in the quote, find the values of each of the following. event that the test result is dirty event that the test result is clean (i) P(TD|D) (ii) P(TDIC) (iii) P(C) (iv) P(D) X X (b) Use the law of total probability to find P(TD). (c) Use Bayes' rule to evaluate P(C|TD). X
