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.

Vitek1552 [10]

Answer:

Step-by-step explanation:

There is not enough information to solve for x.

All we know is that the lines are parallel so the two inner angles will have the same angle measure.

And the angle measures are probably 90 degrees if the transversal (the line cutting through the two parallel lines) is perpendicular to the parallel lines

I hope this helps.
