Flipping 4 fair coins and getting 3 tails
WebSince each coin has 2 possibilities, head or tails, we can do 2*2*2, since there are 3 coins, to find the total number of possibilities. Since there needs to be 2 heads, and there is 3 … WebA biased coin is tossed three times. On each occasion the probability of getting a head is 0.6. a) Draw a tree diagram to show all the possible outcomes after three tosses. Label each branch clearly with the probability of each outcome. b) Using your tree diagram calculate the probability of getting: i) three heads, ii) three tails, iii) at ...

This problem … WebSuppose that we flip a fair coin until either until we have flipped tails twice or we have flipped it six times. (a) After completing this experiment, what are the possible number of times we flipped the coin? (b) What are the probabilities of each of the number of flips cited in part (a)? (c) What is the expected number of times we flip the coin?
WebIf you flip a coin 4 times the probability of you getting at least one heads is 15 in 16 because you times the amount of outcomes you can get by flipping 3 coins by 2, it results in 16 and then you minus 1 from it. With 5 coins to flip you just times 16 by 2 and then minus 1, so it would result with a 31 in 32 chance of getting at least one heads.

WebN=3: To get 3 heads, means that one gets only one tail. This tail can be either the 1st coin, the 2nd coin, the 3rd, or the 4th coin. Thus there are only 4 outcomes which have three heads. The probability is 4/16 = 1/4. N=2: To enumerate directly all the possible outcomes which have exactly 2 heads only, is a bit trickier than the other cases.
