An unfair coin with​ Pr =0.3 is flipped. If the flip results in a​ head, a marble is selected at random from a urn containing fourred and six blue marbles.​ Otherwise, a marble is selected from a different urn containing six red and two blue marbles. If the selected marble selected is​ red, what is the probability that the flip resulted in a​ head? (When you finish, make sure to show your work to the camera for few seconds, submit your work after you finish the exam. Make sure to show the filled tree Diagram)

A pair of dice is rolled and the sum of the numbers is noted.  Determine the probability that one die resulted in a 5 given the sum is 8. Write you answer in decimal.

Technetium-99m is widely used in medical imaging because it emits gamma rays but has a short half-life. Explain why having a short half-life is an advantage in medicine. Why are gamma rays particularly useful for diagnostic imaging compared to alpha or beta radiation?  

What is the rule stating that no two electrons can have the same quantum spin inside an orbital. *answer in all lowercase
