For A coin that comes up heads independently with probability p on each flip what is the variance in the number of flips until the kth head appears ?

The probability of a coin landing on heads is 50%, assuming the coin is fair and has an equal chance of landing on either heads or tails.
To calculate the probability of a coin landing on heads, you can use the formula: Number of desired outcomes / Total number of possible outcomes. In this case, there is 1 desired outcome (heads) out of 2 possible outcomes (heads or tails), giving a probability of 1/2 or 50%.
No, the probability of a coin landing on heads does not change over time. Each flip of a coin is an independent event, meaning the outcome of one flip does not affect the outcome of another. Therefore, the probability remains at 50% for each flip.
As the number of coin flips increases, the probability of getting heads approaches 50%. For example, if you flip a coin 10 times, you could get heads 5 times or more than 5 times, but on average you would get heads 50% of the time.
The weight or size of a coin does not affect the probability of it landing on heads. As long as the coin is fair and has an equal chance of landing on either heads or tails, the probability will remain at 50% regardless of its weight or size.
