Fill in the blank. If any fractions, enter as a slant fraction, for example, 6/7. To receive credit, you must show all of your work and submit in Exam 2 Part B. Solve the problem that involves probabilities with events that are not mutually exclusive. There are 38 chocolates in a box, all identically shaped. There are 8 filled with nuts, 16 with caramel, and 14 are solid chocolate. You randomly select one piece, eat it, and then select a second piece. What is the probability of selecting 2 solid chocolates in a row?

Fill in the blank. To receive credit, you must show all of your work and submit in Exam 2 Part B. Use the Fundamental Counting Principle to solve the problem.  You want to arrange 7 of your favorite CD’s along a shelf. How many different ways can you arrange the CD’s assuming that the order of the CD’s makes a difference to you?

Fill in the blank. If any fractions, enter as a slant fraction, for example, 6/7. To receive credit, you must show all of your work and submit in Exam 2 Part B. Solve the problem involving probabilities with independent events.You are dealt one card from a 52 card deck. Then the card is replaced in the deck, the deck is shuffled, and you draw again. What is the probability of getting a picture card the first time and a club the second time?

Fill in the blanks. To receive credit, you must show all of your work and submit in Exam 2 Part B. Solve the problem that involves computing expected values in a game of chance.One option in a roulette game is to bet on red. (There are 18 red compartments, 18 black compartments, and two compartments that are neither red nor black.) If the ball lands on red, you get to keep the $10 that you paid to play the game and you are awarded $10. If the ball lands elsewhere, you are awarded nothing and the $10 that you bet is collected. What is the expected value for playing roulette if you bet $10 on red? Yes or No: Should you play this game?   

What muscles are involved in a pull-up motion? Also describe the motions performed (flexion, extension, etc.)

A “” refers to the target temperature of the hypothalamus.

Twenty-year-old Kevin had just been diagnosed with acute appendicitis and was waiting to be taken to the operating room (OR). Although he desperately wanted the pain to stop, Kevin was terrified of having general anesthesia. “Does that anesthesia stuff work all the time? How can I not wake up when someone’s slicing my gut open?” In the OR, someone placed a mask over Kevin’s face and when he blinked, he suddenly found himself in a hospital room. “So, it’s over? How did I get here already?” You tell him, “You’ve been out for a few hours. Certain neurons have to depolarize and undergo an action potential to maintain consciousness, but some anesthetics can hyperpolarize them and produce unconsciousness. The anesthetic binds to and opens a certain kind of potassium channel, which increases the “leak” current of potassium. However, it doesn’t affect the voltage-gated potassium channels. This inhibits the neurons, and therefore you aren’t conscious of the surgeons performing the procedure. Amazing!” Questions: 1) What do the terms depolarize and hyperpolarize mean with reference to the membrane potential? 2) Anesthetics hyperpolarize neurons — how does hyperpolarization make it more difficult for neurons to fire? 3) “The anesthetic… increases the leak current of potassium” — how might anesthetics accomplish this? 4) Hyperkalemia is a condition characterized by increased extracellular potassium levels. Would such an individual be MORE or LESS affected by anesthetics? Explain your reasoning.

Multiple sclerosis is an autoimmune disease in which myelin is targeted and destroyed by immune cells. As a nurse, what signs and symptoms would you watch for in a patient with multiple sclerosis? Explain how these S&S occur.
