*Extra Credit Question* You have a patient receiving 40% O2 via a nasal cannula. Barometric pressure is 500 mmHg and Water vapor pressure is 45 mmHg. The patient’s respiratory quotient is 0.8. An ABG was drawn with this results pH 7.38 PaCO2 40 PaO2 80 HCO3 22.   Calculate the Patients’ P(A-a)O2 with correct units of measure.

On a quiz, each question has 4 multiple choice options (1 of which is correct). Let’s say I ran out of time and guessed the last three questions. Let X be the random variable representing the number of correct answers in the last three questions. Which of these options represents the PMF of X?

Suppose that we have a discrete random variable X with PMF and CDF f(x) and F(x), and another discrete random variable Y with PMF and CDF f(y) and F(y). Now we create a new random variable Z in the following way. We have a coin with P(H)=p. We toss the coin once. If it lands heads, then the value of X is determined according to the probability distribution of X. If the coin lands tails, the value of X is determined according to the probability distribution of Y. Find the CDF of X. Hint: Use the law of total probability.
