Please show detailed steps and explanations. A coin lands heads with probability p. Suppose you know that the probability of getting at least one head in two flips of the coin is 9/25. What is the value of p? Solution Let E be the event of getting at least one H in two ?ips. Then Prob E= (1 ? p)^2 = 1 ? 9/25 = 16/25. Hence 1 ? p = 4/5 and p = 1/5 = .2..
