a. Two coins are-tossed together: the chance of one coin landing heads up is b. The chance that both coins will be heads up is _ c. The chance for the rst coin to land heads up and the second coin to land tails up is__.___.. but this probability relates to a specic order (coin 1 landing on heads and coin 2 landing on tails). What about other order com- binations (such as the coin l landing on tails, and coin 2 landing on heads)? How do we calculate the probabilities to include all possible combinations? d. What is the probability of coin l landing on tails and the coin 2 landing on heads?_______ . To calculate the probability of obtaining a heads up coin and tails up coin, independent of order, you need to add the individually probabilities of each event. What is the probability of tossing 2 coins and obtaining a heads 8: a tails? . e. The chance for both coins to fall tails up is the same as for both to be heads, which is. f. To summarize. two coins tossed together many times are expected to fall heads about._.___ of the time. If you state this as a fraction. it is equivalent to
