Question

The biased coin is fipped 4 times. What is the probability that there were no consecutive heads and no consecutive tails? The biased coin is flipped 5 times. What is the probability that there were no consecutive heads and no consecutive tails? The biased coin is flipped n 2 1 times. What is the probability, as a function of n, that there were no consecutive heads and no consecutive tails? Remark: The answers are different for odd n and even n.

Answer 1

The question asks for the probability of not getting consecutive heads or tails when flipping a biased or fair coin multiple times. For a fair coin, the probability of heads or tails is always 0.5. However, the biased coin requires knowledge of its specific probability distribution.

Step-by-step explanation:

The question involves determining the probability of not getting consecutive heads or tails when flipping a biased or fair coin multiple times. The case of the biased coin is more complex as it requires knowledge of the coin's bias, with the probability of heads and tails different from each other. For a fair coin, the events are independent, and the probability of heads is always 0.5, as well as for tails.

To calculate the probability for a fair coin flipped n times without consecutive heads or tails, one could identify the permissible sequences that fit the criteria and then calculate the probabilities of each sequence occurring.

For the biased coin, we'd have to consider the actual probabilities of heads and tails which were defined in a given example (P(heads) = 3/7, P(tails) = 4/7) to calculate the expected payout and to determine the probability for sequences without consecutive results. The calculations get complex as the number of flips increases and require a methodical approach to list possible sequences and then apply the specific probabilities.
