In a recent year, a basketball player had a 65% success rate on free throws. When he made his first free throw, he successfully made the second free throw 85% of the time. However, when he missed the first free throw, he successfully made the second free throw only 50% of the time.
Write the three probability notation statements.
P(make a free throw) = 0.65
P(made second free throw | made first free throw) = 0.85
P(made second free throw | missed first free throw) = 0.5

Create a tree diagram for the following example:
Sophia reads books on 50% of her free weekends. If she reads, there is a 0.80 probability that she feels relaxed by Sunday evening. If she doesn’t read, there is a 0.60 probability that she feels relaxed by Sunday evening. Suppose we select a random weekend and record whether Sophia reads and whether she feels relaxed.
weekend
reads 0.5 : feels relaxed 0.8 : doesn't feel relaxed 0.2
doesn't read 0.5 : doesn't feel relaxed 0.6 :
feels relaxed 0.4

How many branches should be on the tree diagram for this example: Suppose that 5% of athletes at a certain university are using steroids or other performance-enhancing drugs (PEDs). Unfortunately, the tests used to detect steroids aren’t perfect. Suppose that 3% of athletes who are not using steroids will test positive and be accused of using steroids. Meanwhile, 1% of athletes who are using steroids will test negative and escape detection.

Alex plays video games on 60% of his free evenings. If he plays video games, there is a 0.70 probability that he completes his homework on time. If he doesn’t play video games, there is a 0.90 probability that he completes his homework on time. Create a tree diagram for this scenario.
Evening choice -->
play video games (0.6) --> completes HW (0.7)
--> doesn't complete HW(0.3)
doesn't play VG (0.4)--> completes HW (0.9)
--> doesn't complete HW (0.1)
