Examples include the Monty Hall paradox and the birthday problem. Probability can be loosely defined as the chance that an event will happen.Correct answer: 0.031. Explanation: Probability of each event = (# green marbles + # blue marbles)/ Total # of Marbles. P1 = (15 + 25) / 125 = 40 / 125. Second event assumes a blue or green was chosen for first event so there is one fewer marble on top and also one fewer marble in the total number of marbles.Practice Problems on Probability is the ultimate study guide and practice problem set for teaching your students probability.I don't know what it is about probability that really boggles their mind!
