The probability of getting 2 heads and 1 tail when three coins are tossed is 3 in 8. Find the odds of not getting 2 heads and 1 tail. ANSWER: 5:8?Three Coins are tossed. Find the probability that exactly 2 coins show heads if the first coin shows heads.?ANSWERS: Could it be 1/4?

Franklin has three coins, two fair coins (head on one side and tail on the other side) and one two-headed coin. 1) He randomly picks one, flips it and gets a head. What is the probability that the coin is a fair one? 2) He randomly picks one, flips it twice. Compute the probability that he gets two tails. 3) He randomly picks one and flips it twice. Suppose B stands for the event that the first result is head, and...
Suppose two fair coins are tossed and the upper faces are observed. Let A denote the event that exactly one head is observed and B the event that at least one head is observed. List the sample points in both A and B.
Use the formula for the probability of the complement of an event. Two dice are tossed. What is the probability of not getting a sum of 5? (Enter your probability as a fraction.)
Use the formula for the probability of the complement of an event. Two dice are tossed. What is the probability of not getting a sum of 7? (Enter your probability as a fraction.)
5. For the each of the three parts, (i) Write, in words, the complement of each event. (ii) List all outcomes in the complement. (a) You flip two coins and at most one head comes up. (Again, look at the prompt above.) (b) You roll two dice and no 5' appears. (3.3.2) (c) A basketball player will miss at least one of the next three free throws. (3.3.3) For each of the following three problems, suppose a couple has three...
