If Albert Enstein has 53 socks in his drawer: 21 identical blue, 15 identical black and 17 identical red. The lights are out and he is completely in the dark. How many socks must he take out to make 100 percent certain he has at least one pair of black socks?

Answers

Answer 1

Answer:

6  socks

Step-by-step explanation:

What we must do is calculate the probability of this happening, that he takes out two black socks in the first two taken out.

There are 12 black socks and in total they are 24, therefore the probability of drawing 1 is:

12/24

and now the probability of getting another one is 11 (there is one less outside) and in total they are 23:

11/23

the final probability is the multiplication of these events:

(12/24) * (11/23)

P = 0.24

Now, to know how many you should get, we multiply the probability by the total number of socks, that is:

0.24 * 24 = 5.76

So you must take out at least 6 socks for the above to happen.

Answer 2

the number of socks  Albert Enstein has to take out to be sure that he has at least one pair of black socks is 38.

In order to determine the number of socks  Albert Enstein has to take out to be sure that he has at least one pair of black socks, we would have to add the number of blue socks with the number of red socks.

Number of socks to be taken out = number of blue socks + number of red socks

21 + 17 = 38 socks

Answer:

10/27

Step-by-step explanation:

To figure this out, first subtract 8/15 from 6/5.

Before we can do that though, we need a common denominator. The LCM of 5 and 15 is 15. (5 * 3 = 15; 15 * 1 = 15) 8/15 already has 15 has a denominator, so that doesn't need to be modified. 6/5 becomes 18/15 (6 * 3 = 18).

Subtract 8/15 from 18/15 to get 10/15. This simplifies to 2/3.

Now, multiply 2/3 by 5/9 (reciprocal of 9/5). That equals 10/27. There is no need to reduce, as it is already simplified.

Hello, I would really like some help on this!! Please leave an explanation of how you got your answer! Thank You!

Answers

1a) To find the total area, you must find the area of the triangular part that is missing, then subtract this from the area of the rectangle. For the triangle’s area, you need to know the width (2m) and length (2m). For the rectangle’s area you need to know the width (3m) and length (4m).
1b) the total area is 10m^2 (10 meters squared). This is found by subtracting the triangle (.5x2x2=2) from the rectangle (3x4=12).
