In a standard deck of cards, there are 13 diamond cards and 39 non diamonds. To choose 3 diamonds from 13 cards would be equivalent to 13*12*11 as there are less cards to choose from each time you remove a card. To choose two non diamonds from the other non diamonds cards would be equivalent to 39*38, taking into account the number of cards you remove each time you pick out one card. Hence the total number of ways is 13x12x11x39x38.

Answer:
The answer is option (D). 4+b=16;b=12 more books
Step-by-step explanation:
Step 1: Derive expression for total number of books to be read
The expression for the total number of books to be read is;
T=a+b.... equation 1
where;
T=total number of books to be read
a=total number of books already read
b=number of books not read
In our case;
T=16 books
a=4 books
b=unknown
replacing;
16=4+b
4+b=16...equation 2
solving;
b=16-4
b=12
You need to read 12 more books to reach your target
