12. [-/5 Points] DETAILS BBUNDERSTAT13 5.R.019. 0/6 Submissions Used An experiment consists of tossing an unfair coin (60% chance of landing on heads) a specified number of times and recording the outcomes. (a) What is the probability that the first head will occur on the second trial? (Enter your answer to four decimal places.) (b) Does the probability of the first head occuring on the last toss change if we toss the coin three times? What if we toss the coin four times? O The probability does not change for either three or four tosses. The probability changes if we toss the coin four times, but does not change if we toss the coin three times. The probability changes for both three and four tosses. The probability changes if we toss the coin three times, but does not change if we toss the coin four times. What probability distribution model do we use to compute these probabilities? O binomial O geometric O Poisson O normal What is the probability that the first head will occur on the fourth trial? (Round your answer to four decimal places.) P(4) = What is the probability that the first head will occur after the fourth trial? (Round your answer to four decimal places.) P(n = 4) =
