**Problem 9: Sock Probability**

A bureau drawer contains 10 black socks and 12 brown socks. The owner of these socks is a very early riser who selects the socks in the dark.

**Task:**
Draw the probability tree for drawing two socks from the drawer without replacement and use the tree to find the probabilities of the following events:

a) Selecting 2 socks and having both black.

b) Selecting 2 socks and obtaining 1 black and 1 brown.

c) Selecting 3 socks and obtaining at least 2 of the same color.
*Do not add a layer to the tree for this draw... just think about it.*

---

This problem involves calculating probabilities using a probability tree, focusing on combinations and outcomes of selecting socks of different colors from the drawer.

A particular station says that the probability that an incoming call is for medical assistance is 0.72. This can expressed as P(call is for medical assistance) = 0.72. Assume each call is independent of other calls. a) Interpret the probability that an incoming call is for medical assistance. b) What is the probability that none of the next four calls are for medical assistance. c) You want to estimate the probability that exactly three of the next four calls are for medical assistance. Describe how you would use the table of random digits to simulate this probability. (Remember that after reaching 4 different numbers, check for exactly 3 calls for medical assistance, then repeat)

A magician appears to be using a biased coin during one of their magic tricks. To find out whether this is true, the alleged unfair coin is flipped twice. The tree diagram below shows the probabilities of the different outcomes. A tree diagram has a root that splits into 2 branches representing the outcomes of an event labeled Upper H and Upper T with probabilities StartFraction 3 Over 8 EndFraction and StartFraction 5 Over 8 EndFraction respectively. Each primary branch splits into 2 secondary branches, labeled Upper H and Upper T. The secondary branches have the following probabilities, with the primary and secondary branches listed first and the probability listed second: Upper H Upper H, StartFraction 3 Over 8 EndFraction; Upper H Upper T, StartFraction 5 Over 8 EndFraction; Upper T Upper H, StartFraction 3 Over 8 EndFraction; Upper T Upper T, StartFraction 5 Over 8 EndFraction. Use the diagram to find the probability of getting one head and one tail (in either order).
