You perform an experiment that, based on experience from your lab mates, should lead to a success in 2 out of 3 cases. You perform the experiment three times in a row and all experiments fail. Assuming that your lab mates are correct, what is the probability of three consecutively failing experiments?

You know the probability distribution p(x)p(x) of a random variable xx, which is defined in the interval a≤x≤ba \le x \le b. You are interested in a function f=f(x)f=f(x) that directly depends on the variable xx. How do you calculate the expected average result for f(x)f(x)?

Carbon tetrachloride or tetrachloromethane (CCl4_4) is a liquid compound that was formerly used as a precursor for refrigerants, as an anti-parasitic agent, or as a component of hard-surface cleaners. However, after the discovery of serious health and environmental dangers associated with CCl4_4 its use is now limited to specialized industrial applications. We learned during the lecture that chlorine atoms naturally occur as a mix of isotopes with relative abundances of: 35^{35}Cl: ≈0.75=75%=3/4\approx 0.75 = 75\% = 3/4 37^{37}Cl: ≈0.25=25%=1/4\approx 0.25 = 25\% = 1/4 What is the probability to find exactly one 37^{37}Cl atoms in a single CCl4_4 molecule?

A nurse is caring for a client with type AB+ blood who has a hemoglobin level of 7.9 g/dL. The nurse began a packed red blood cell transfusion of type AB- blood at 1600. The nurse records the client’s vital signs throughout the first 30-minutes of the transfusion.  Thirty minutes into the transfusion, the client complains of chills and a headache. She denies urticaria, flank pain, and dyspnea.  Based on the client’s findings, the nurse suspects which type of transfusion reaction?
