Due to current pandemic we are having online classes, Harish is also having online classes. He is having a quiz this weekend. In the quiz, Harish either guesses (or) copies from net(or) knows the answer to a multiple-choice question with 4 choices. Probability that he makes a guess is 1/3. He copies the answer is 1/6. The probability that his answer is correct given that he copied it is 1/8. Find the probability that he knew the answer to the question. Given that he correctly answered it.

Two dice are rolled at the same time. Find the probability of each event listed when the probability is given as P(die 1, die 2). For example, if you want to know the probability that you roll a 3 on the first die and and a 5 on the second die, it would be written as P(3, 5). Give your answer as a decimal rounded to the thousandth place (three numbers after the decimal). P(1, 1) = P(both odd) P(even, odd): P(2 anywhere) = P(sum of 8) = P(sum of 1) =

If the odds in favor of event E are a to b the probability of the event is given by P(E) = a/(a+b) Choose one of the causes of death from the article and convert odds to probability - determine the probability of this cause of death. Determine the probability that the cause of death is not the one you chose. Explain why it is so difficult to calculate this probability directly yet so easy to calculate it using a trick.You can chose which death or you can do for drowning doesnt matter.
Nissa is randomly pulling the medical records of a hospital's patients and collecting the records of those who have multiple stays at this hospital. Assume that 27% of all patients who have ever stayed at this hospital have multiple stays. What is the probability that the first multiple stays patient record that Nissa comes across is the fourth one she pulls? Use a TI-83, TI-83 Plus, or TI-84 calculator to find the probability. • Round your answer to three decimal places.
