Answer:

0.5578

Step-by-step explanation:

Fingerprint correctly match 92 % of the time.

A novice that will correctly identify a match 75​% the time.

Each of the attempts of matching a fingerprint with the individual is independent.

The number of pairs are 7.

a). So the probability that the expert will identify every pair correctly is

= 0.92 x 0.92 x 0.92 x 0.92 x 0.92 x 0.92 x 0.92= 0.927 = 0.5578

andrews book collection contains 60 books.he donates 15% of his books yo the national library,sells 1/4 of his books to a book d
Vitek1552 [10]

Answer:

Books remaining in  Andrews book collection = 29 books

Explanation:

 Andrews book collection contains 60 books.

 He donates 15% of his books to the national library,

        Number of books to library = 60 x 15/100 = 9

 Sells 1/4 of his books to a book dealer,

        Book sold to book dealer = 60 x 1/4 = 15

 Sells 7 books on amazon.

 Books remaining = 60 - (9 + 15 + 7)

                              = 60 - 31

                              = 29

Books remaining in  Andrews book collection = 29 books
