Practice and Problem Solving: A/B. Determine the probability of each event. Write impossible, unlikely, as likely as not, likely, or certain. Then, tell whether the probability is 0, close to 0, 1 , close to 1, or 1. 2. 1. randomly picking a blue card from a bag containing all blue cards.
In order to describe an unfair die properly, we must specify the probability for each of the six possible outcomes. The following table gives answers for each of 4 different dice.
Probability pdf. Examples. Workout. Click here. Question 1: Theo has 3 red sweets and 2 white sweets. He picks a sweet at random. (a) Write down the probability that Theo picks a red sweet. (b) Write down the probability that Theo picks a white sweet. Question 2: Leah has 12 cards, each with a shape on it. She takes a card at random.
Introduction. This chapter introduces students to counting techniques necessary for the study of probability. How many outcomes are possible when rolling two dice? when flipping four coins? when drawing five cards from a deck of 52?
Easy and Medium Di culty Problems. Problem 1. Suppose we ip a fair coin once and observe either T for \tails" or H for \heads." Let X1 denote the random variable that equals 0 when we observe tails and equals 1 when we observe heads. (This is called a Bernoulli random variable.)
5) A marble is drawn randomly from a jar that contains 3 yellow marbles, 2 white balls, and 4 red marbles. Find the probability of selecting. a) a marble that is not yellow. b) a yellow or red marble. c) a black marble.
