Suppose that we flip a coin 12 times independently. The probability of coming up heads is 0.45 and tails is 0.55 for this coin. What is the probability that we observe 7 heads? Suppose that we flip a coin independently, where the probability of coming up heads is 0.45 and tails is 0.55. What is the probability that we observe the first head in the fifth flip?
