Answer 1

Answer #1

P(head), p = 0.5

T stands for tail and H stands for head.

P(first heads on 4th attempt) = P(TTTH) = P(T) * P(T) * P(T) * P(H) = 0.5 * 0.5 * 0.5 * 0.5 = 0.0625

Assume that a coin is flipped where the probability of coin lands "Heads" is 0.49. The coin is flipped once more. This time, the probability of obtaining the first flip's result is 0.38. The random variable X is defined as the total number of heads observed in two flips. On the other hand, the random variable Y is defined as the absolute difference between the total number of heads and the total number of tails observed in two flips. Calculate...
