ratelena [41]
Given:
2002 sold 1000 paperback books and 1500 hardback books for a total of 2,500 books.

2003 sold 15% more paperback books and 5% more hardback books.
1000 x 1.15 = 1,150 paperbacks
1500 x 1.05 = 1,575 hardbacks

1150 + 1575 = 2,725

2,725 - 2,500 = 225
225 / 2,500 = 0.09
0.09 x 100% = 9%  choice C

We draw 2 cards from a deck of 52 cards. what is the probability that both are queens?
solniwko [45]
Use combination
There are 4 queen cards in a deck of 52 cards
Probability = 4C2 / 52C2

I calculate 4C2 first
4C2 = 4! / (2! 2!)
4C2 = (4 × 3 × 2 × 1) / (2 × 1 × 2 × 1)
4C2 = 6

Then I calculate 52C2
52C2 = 52! / (50! 2!)
52C2 = (52 × 51)/2
52C2 = 1.326

Hence, the probability is
Probability = 4C2 / 52C2
Probability = 6/1,326
Probability = 1/221
