3cards are chosen at random from a standard 52-card deck. what is the probability that they form a pair? (a 3-card hand is a 'pair' if two of the cards match in rank but the third card is different. for example, 668 is a pair, but 999 is not.)

Hello!

First of all, we have a 4/52, or 1/13 chance of selecting a pair. Then, we select 1/3 cards 3 times, so we use this as our other fraction.

=

Therefore, we have a 1/39 or about 3%.

I hope this helps!

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
