The probability of obtaining a grid that does not have a 2-by-2 red square 16 2/3%

probability : The probability of an event can be calculated by means of probability formula via honestly dividing the favorable quantity of outcomes by way of the total variety of viable consequences.

<u>Step-by using-step clarification:</u>

<u>given that:</u>

form are both square or circle with both equally likely :

for this reason,

P(square) = half of ; P(circle) = half of

color are either blue, pink or inexperienced with the 3 equally likely ;

P(purple) = 1/3 ; P(green) = 1/three ; P(blue) = 1/three

chance of creating a inexperienced circle :

independent probability

P(green n circle) = p(inexperienced) * p(circle)

P(green n circle) = 1/3 * half of

P(green n circle) = 1/6

= 0.16666

(0.16666 * 100%) = 16.6666%

= 16 2/3%

The High Roller, a giant ferris wheel in Las Vagas, casts a 242-foot shadow. A 6’3” tall man standing nearby casts a 2 3/4-foot
Ira Lisetskai [31]

Answer:

550ft

Step-by-step explanation:

Simple napkin math, so you know what both shadows are you need to find how tall the High Roller is we will use X for this.

\frac{242ft}{6'3"}  x \frac{x}{2'9"}

Im not 100% I set it up right but essentially 242 divided by 2'9" and that equals 88

Take 88 and multiply that by 6'3" and you get your Height for the High Roller

What I did their was I scaled the humans height to that of the High Roller dividing it gives you a number you can use to scale the height of that human to how it should scale to the High Roller, which is why I took 88 and multiplied it by the human's height.

Hope this helped :)

Answer:

15n=135

Step-by-step explanation:

first, you need to know how much of the total amount is the money needed for soccer balls, to find this you take the amount of a soccer ball and multiple it by the amount of people

14×15=210

then you subtract that from the total amount to get the amount spent on jerseys.

345-210=135

to get the amount of each jersey you take 135 and divide by the amount of people

135÷15=9
