We are back to our old friends: center, shape, and spread. We won't worry about shape too much today, but let's use these formulas to help describe a distribution. If you see 50 trees on your walk, what is the probability that 6 or fewer have a star on top? (Round to 3 decimals) Suppose that 15% of Christmas trees have a star on top. You go through a walk in your neighborhood. Submit We will make our usual assumptions that the trees are independent from each other and that this probability is fixed. What are the chances that it takes 4 or more trees until you first see one with a star on top?(Round to 3 decimals) Hint: Think complement! Submit What are the chances that you don't see a tree with a star on top until the third tree? (Round to 3 decimals)
