Since there are two black queens out of 52 cards, there is a 2/52 chance of drawing a black queen first. This is equivalent to a 1/26 chance.
Now that we have removed a black queen, there are 51 cards left in the deck. 26 of them are red because we only took away a black card. This means that there is a 26/51 of drawing a red card next.
In order to find the probability of both of these happening, we multiply the two together. 1/26 * 26/51 = 26/1326. This reduces to 1/51. So, there is a 1/51 chance of drawing a black queen, then a red card.

Answer:
<em>132</em>
<em />
Explanation:
All you need to do is separately find the area of the shapes that are part of the figure (in this case the trapezoid and rectangle), and then add them all up.
1.(7x4) + (1/2x8[7+19])
2. 28 + 104
3. 132

concentration
Step-by-step explanation:
Because concentration is a factor to how much of a volume to give
Answer:
x = 2 is a solution
x = 0 is an extraneous solution
(Option 2)
Step-by-step explanation:
4/x = (3x + 2)/x²
4x² = 3x² + 2x
x² - 2x = 0
x(x - 2) = 0
x = 0, x = 2
Verification:
4/x = (3x + 2)/x²
At x = 2
4/2 = [3(2) + 2]/2²
2 = 8/4
2 = 2
At x = 0
4/0 = [3(0) + 2]/0²
Is undefined
