Consider the experiment of drawing two cards from the top of a standard deck of 52 cards, and the event e of the two cards having the same value. a. if we're drawing two cards from a deck of 52, what is the structure? what is n and r? this will be the size of the sample space, n(s) b. use combinatorics to figure out the amount of outcomes, n(e), that result in e being successful. (i. e., how do calculate the amount of outcomes where two cards have the same values? )

a) For this case the sample space consists of all the possible pairs of cards, and for this case the order no matter. We need to remember that a standard deck consists of 13 hearts, 13 Clubs, 13 Diamonds and 13 Spades with possible options on each denominaton (A,2,3,4,5,6,7,8,9,10,J,Q,K).

If we want to define the structure for this we can find the size of the sample size using combinatories with the following formula:

For our case we want to select r =2 cards from n = 52 in total to then we have this:

possible pairs.

b)  

E= draw a pair with the two cars of the same value.

See complete explanation below.

Step-by-step explanation:

Part a

For this case the sample space consists of all the possible pairs of cards, and for this case the order no matter. We need to remember that a standard deck consists of 13 hearts, 13 Clubs, 13 Diamonds and 13 Spades with possible options on each denominaton (A,2,3,4,5,6,7,8,9,10,J,Q,K).

If we want to define the structure for this we can find the size of the sample size using combinatories with the following formula:

Part b

For our case we want to select r =2 cards from n = 52 in total to then we have this:

possible pairs.

So then And let define the event:

E= draw a pair with the two cars of the same value.

From definition of probability:

The total outcomes for this case are 1326 and the possible would be 13*6= 78.

The 6 is because for any pair of any card we have 4C2 ways to obtain a pair, because we have a total of 4 cards for each possible outcome, and:

And the 13 is because we have 13 possible cards on the standard deck. So then we can find:

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
