Answer:
Its B. two
Step-by-step explanation:
9·2 =18 and 18-2 =16
6g + 4(-5+4g) = 1 - g
6g - 20 + 16g = 1 - g
22g - 20 = 1 - g
22g + g = 1 + 20
23g = 21
g = 21/23 or 0.913043 in decimal form.

There are four 7's in a standard card. Chance of getting a 7 first is 4/52 = 1/13
There are four queens in a standard card. Chance of getting a queen in the second drawing is 4/51 and chance of getting a queen in the third drawing is 3/50.
Therefore, chance of drawing a seven and two queens is 1/13 x 4/51 x 3/50 = 2/5525
