A study by a reputable research organization found that when presented with prints from the same​ individual, a fingerprint expert will correctly identify the match 91​% of the time. In​ contrast, a novice will correctly identify the match 77​% of the time. Consider a sample of seven different pairs of​ fingerprints, where each pair is a match. Complete parts a and b below.         a. What is the probability that an expert will correctly identify the match in all seven pairs of​ fingerprints?   The probability is enter your response here. ​(Round to four decimal places as​ needed.)   b. What is the probability that a novice will correctly identify the match in all seven pairs of​ fingerprints?   The probability is enter your response here. ​(Round to four decimal places as​ needed.)
