What is the probability that both coins are heads knowing that one of the coins is showing heads?

What is the probability that both coins are heads knowing that one of the coins is showing heads?

If you answer heads, then the conditional probability that both coins are heads is 1/2. More generally, if you flip two coins and someone asks you to tell them the status of one of the coins, the conditional probability if you say heads depends on the rule you use to answer the question.

What are the possible outcomes of tossing 2 coins?

When we toss two coins simultaneously then the possible of outcomes are: (two heads) or (one head and one tail) or (two tails) i.e., in short (H, H) or (H, T) or (T, T) respectively; where H is denoted for head and T is denoted for tail.

What is the probability of getting exactly 2 heads in tossing of a coin thrice?

1/2
Answer: If you flip a coin 3 times, the probability of getting at least 2 heads is 1/2.

When 2 coins are flipped What is the probability of getting?

The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25. The second useful rule is the Sum Rule.

When flipping two coins What is the probability that both coins land on heads or both coins land on tails?

Previous outcomes do not affect current or future outcomes in any way. No matter how many times in a row a coin lands tails up, there is still only a 50% chance that it will land heads up on the next flip. probability of both being heads (or tails) is . 50 × .

What is the probability when two coins are tossed?

1/4
Summary: If two coins are tossed in the air, the probability that both coins will land on “heads” is 1/4.

What is the probability of a coin coming up heads twice?

When you flip a coin four times, what is the probability that it will come up heads exactly twice? Thus the probability is: 2 / 8 = 0.25 but the correct answer is 0.375. Can anyone explain why I’m wrong?

What is the probability that at least one of them was heads?

Both HT and TH will result in the other coin being a tail and only the HH will result in the other coin being a head so it is 1 good outcome out of 3 possible and they are all equally likely so the correct answer is 1 / 3 probability. Done! It depends on how you came by the information that “at least one of them was heads”.

How many possible outcomes are there if two coins are flipped?

How many possible outcomes are there if two coins are flipped and a dice is rolled? When you flip a coin there are two possible outcomes (heads or tails) and when you roll a die there are six outcomes (1 to 6). Putting these together means you have a total of 2×6=12 outcomes.

What is the probability of flipping heads 6 times in a row?

Flipping or tossing of a fair coin are an independent process. Probability of flipping heads 6 times in a row by a fair coin = 1/2⁶ = 1/64 . What is the probability of obtaining ten heads in a row when flipping a coin interpret this probability?
