25% because if you have 4 cards which would equal 100% and you are dealt 2 you have a 25% chance of getting any of the 4. (25x4=100)
But, if you are talking about probability of color it would be 50% because if you have 2 red cards and the total deck is 4 cards, then that is already half of the deck. And if you have 2 black cards then that makes up the other half. but if you are talking individually like Red 1 and Red 2 and Black 1 and Black 2 separating them would create a 25% probability. So, x= 25% (infivudually) or 50% (by color)

Answer:

\sqrt{118}<em> or 10.8627805 </em>

Step-by-step explanation:

Start by taking the difference of each value of both points

<u>Find the difference in x values </u>

78-2 = 76

<u>Find the difference in y values</u>

46-4 = 42

<u>Add the two differences </u>

76+42=118

<u>Take the square root of this value </u>
