When a coin tossed 12 times?Summary: A coin is tossed 12 times, the probability of getting a head is 5/12.
When flipping a fair coin 10 times what is the probability of at least one head?The probability of getting at least one head in 10 tosses is ≈0.999 .
How likely is it that a fair coin will land on heads every time if it is tossed 10 times?Junho: According to probability, there is a 1/1024 chance of getting 10 consecutive heads (in a run of 10 flips in a row). However, this does not mean that it will be exactly that number. It might take one person less throws to get 10 consecutive heads.
What is the expected number of heads that come up when a fair coin is flipped ten times?What is the expected number of heads when it's flipped 10 times? You can use an argument like that given in 2 using linearity of expectation, above, to see that the expectation is 10 times the expectation of H on one flip, that is, 10 times 0.6. So the answer is 6.
