Pamela is doing a probability experiment with a box of colored paperclips comprised of red, green, blue, and yellow paperclips.

She is drawing a paperclip at random from the box and records the color before returning the paperclip to the box. Her results are shown in the table below.
Color Number of
Times Drawn
Red 44
Green 38
Blue 42
Yellow 36

Complete the following sentences based on the outcomes in the table.

If a paperclip is drawn a total of 800 times, a yellow paperclip is expected to be drawn roughly
times.

If a paperclip is drawn a total of 80 times, a blue paper clip is expected to be drawn roughly
times.

If a paperclip is drawn a total of
times, a green paper clip is expected to be drawn roughly 1,235 times.

The probability of tossing heads with a standard coin is 1/2, because it is one of two possible outcomes. The probability of tos
spayn [35]

Answer:

  a) 1/64

  b) 1/4096

Step-by-step explanation:

As you can tell from the example, the exponent of 1/2 is the number of heads in a row.

a) p(6 heads in a row) = (1/2)^6 = 1/(2^6) = 1/64

b) p(12 heads in a row) = (1/2)^12 = 1/(2^12) = 1/4096

_____

<em>Additional comment</em>

The probability of a head is 1/2 because we generally are concerned with a "fair coin." That is defined as a coin in which each of the 2 possible outcomes has the same probability, 1/2. Similarly, a "fair number cube" has 6 faces, and the probability of each is defined to be the same as any other, 1/6. Loaded dice and unfair coins do sometimes show up in probability problems.

Im giving 30 points pls help
gayaneshka [121]

Step-by-step explanation:

Pathagory and Theorem

a^2+b^2=c^2

(x-3)^2+(x-4)^2=6^2

expand:

2x^2-14x+25=36

2x^2-14x-11=0

x=(\sqrt{71}+7)/2

perimeter=(x-3)+(x-4)+6=2x-1

insert the value for x into 2x-1

\sqrt{71}+6=perimeter

Hope that helps :)
