MAT 133 5-3 Homework Assignment Solutions (MAT 133-J4254) Oxnard Petro Ltd. is buying hurricane insurance for its off-coast oil drilling platform. During the next five years, the probability of total loss of only the above-water superstructure ($250 million) is .30, the probability of total loss of the facility ($950 million) is .30, and the probability of no loss is .40. Find the expected loss. Expected loss is the same as the mean. We have 3 different x-values here because we have 3 diff...

4-3 Homework Help MAT 133-J4254 | Questions with Solutions. Suppose the probability of an IRS audit is 1.4 percent for U.S. taxpayers who file form 1040 and who earned $100,000 or more. (a) What are the odds that such a taxpayer will be audited? P(A) = P(the taxpayer will be audited): 1.4% → .014 P(A’) = P(the taxpayer won’t be audited) = 1 - .014 = .986 b) What are the odds against such a taxpayer being audited? Here is a video you can watch for Problem 2: Homework Problem 3 Reca...

MAT 133 4-3 Homework Help | Questions with Solutions. So you need to multiply your individual probabilities together to see if it equals the probability of them both happening. Which pairs of events are independent? P(J) = .50, P(K) = .40, P(J ∩ K) = .3. P(J) ×P(K) = .5 ×.4 =.2 and P(J ∩ K) = .3, therefore J and K are not independent. P(J) = .60, P(K) = .20, P(J ∩ K) = .12. P(J) × P(K) = .6 ×.2 =.12 and P(J ∩ K) = .12, therefore J and K are independent. P(J) = .15, P(K) = .5,...

MATH MAT 133 5-3 Homework Assignment Solutions. Homework Problem 7 Find the mean (2 decimal places) and standard deviation (4 decimal places) for each binomial random variable. This is a binomial problem.  n = number of trials  p = probability of success (Your text uses the symbol pi instead of p)  q = 1 - p which is the probability of failure. There are formulas for the mean & standard deviation. To find the mean.  Multiply n•p. To find the standard deviation.  Mult...
