Suppose that you flip five fair coins and roll three fair dices at the same time and all the events are independent. (a) What is the probability that exactly two coins land heads up and one dice shows a six? (b) What is the probability that at least four coins land heads up and two dices show a number less than three? (c) What is the probability that the total number of heads is an even-number and the addition of...

Suppose you flip three fair, mutually independent coins. Define the following events: Let A be the event that the first coin is heads. Let B be the event that the second coin is heads. Let C be the event that the third coin is heads. Let D be the event that an even number of coins are heads. Determine the probability space for this experiment (build the probability tree). Using the probability tree, find the probability of each of the...

Suppose you have two coins. One coin is fair and other is a coin with heads on both sides. Now you choose a coin at random and flip the coin. If the coin lands head, what is the probability that it was the fair coin?

Problem 2 Suppose you flip a penny and a dime. Each coin is equally likely to come up heads and tails. The two flips are independent a) What is the sample space? b) What is the conditional probability that both coins come up heads, given that the penny comes up heads? c) What is the conditional probability that both coins come up heads, given that at least one of the coins comes up heads? (Hint: the answers in part (b)...
