Your friend has two standard decks of 52 playing cards and asks you to randomly draw one card from each deck. What is the probab

dem82 [27]

Answer:

Hence the probability of getting 2 spades will be 1/16

Step-by-step explanation:

Given:

Two deck if playing cards

To Find:

Probability that will get two spades

Solution:

As we know that ,there 52 playing cards in a deck

and 13 of that are spades

So probability of getting spade from a deck is ,

P(spades)=total number of spades /Total number of cards.

P=13/52

P=1/4

Similar for the second deck of card,

Required probability is that , getting spades from each deck

It is given by,

Required probability =Probability of spades in 1st AND Probability of spade in 2nd deck

As there is use of AND operator there should multiplication of two events,

Required probability =1/4*1/4

=1/16

Resident always seems to have a dirty truck his girlfriend gave him a gift card to car wash after three carwashes rest at 61.75

Llana [10]

I’m thinking it’s $100. I guessed 100 first as that is a pretty common number and subtracted 61.75. I was left with 38.25 and I divided that by 3, the amount of washes. I got $12.75 but I had to check since I guessed 100. I then subtracted 23.50 from 100 and got 76.5. I divided that by 6, the amount of washes, and got 12.75 again. So I’m pretty sure that there was $100 on the gift card before he washes his car six times, each wash being $12.75.

For multiplication: x ∙ y = y ∙ x

Example 1:

For addition: x + y = y + x

Example 2:

Notice that numbers don’t commute under the operation of subtraction

My question is in the picture pls help

Liono4ka [1.6K]

So basically there are four sides. 51 1/8 + 51 1/8 because two sides are that length. the answer in decimal form would be 102.25. now do 38 1/4 + 38 1/4 = 76.50. the answer is 178.75 feet.

20 points One diagonal of a rhombus has endpoints (-10, 1) and (2, 9).

Makovka662 [10]

Check the picture below.

so as you already know, a rhombus is a parallelogram whose sides are equal, so the distance from say (-10, 1) to either endpoint of the other diagonal must be the same.

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-10}~,~\stackrel{y_1}{1})\qquad \underline{(\stackrel{x_2}{-2}~,~\stackrel{y_2}{2})}\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{[-2-(-10)]^2+[2-1]^2}\implies d=\sqrt{(-2+10)^2+(2-1)^2} \\\\\\ d=\sqrt{64+1}\implies \boxed{d=\sqrt{65}} \\\\[-0.35em] ~\dotfill$

$\bf (\stackrel{x_1}{-10}~,~\stackrel{y_1}{1})\qquad \underline{(\stackrel{x_2}{-6}~,~\stackrel{y_2}{8})}\qquad \qquad d=\sqrt{[-6-(-10)]^2+[8-1]^2} \\\\\\ d=\sqrt{(-6+10)^2+(8-1)^2}\implies d=\sqrt{16+49}\implies \boxed{d=\sqrt{65}}$
