STAT 155 Introductory Statistics Lecture 13: Birthday Problem
... • In a classroom of 45 people, what is the probability that at least two people have the same birthday? • Event A: at least two people have the same birthday out of the 45 people. • AC: every person has a different birthday out of the 45 people. • P(A) = 1 - P(AC) = … (see the board) ...

... For r > 12 , it will always make sense (in terms of expected amount received) to switch envelopes upon looking in one. Eckhardt moves quickly from the general problem formulation to analyzing this particular model. I agree with him that the behavior of the model is a bit surprising. Note, however, t ...

Suppose we define the random variable Y = the number of cars the collector counts until he gets a red-headed driver for the first time. Is Y a geometric rand ...

... Random variables can be discrete, e.g. a count of the heads in six flipped coins, or continuous, e.g. the temperature during a day. 7.1.1. Let s ∈ S, then P(x = a) ≡ P({s | X(s) = a}), and P(a ≤ X ≤ b) ≡ P({s | a ≤ X(s) ≤ b}) 7.2. Suppose a discrete random variable X can only take on the values x1, ...

Let’s say that on average, 100 pellets fall on a square meter. What is the probability that 80 pellets or less fall on some square meter? The average ...
