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
All I can see is the equation. What is it asking?

In economics growth period, when pricing are rising too rapidly, in order to stabilize prices, Federal Reserve should raise the discount rates.
Answer:
A. -1≤x≤6
Step-by-step explanation:
- 6≥ x² - 5x
- x² - 5x -6 ≤ 0
- (x-6)(x+1) ≤ 0
- x - 6 ≤ 0 ⇒ x ≤ 6
- x + 1 ≥ 0 ⇒ x ≥ -1
- -1 ≤ x ≤ 6
Choice A is the answer
