Step-by-step explanation:
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%

Answer: 0.1840
Step-by-step explanation:
The binomial probability formula :-
, here n is the number total of trials , p is the probability of getting success in each trial and P(x) is the probability of getting success in x trial.
Given : The probability of the community favored building a police substation in their neighborhood = 0.64
If 14 citizens are chosen, then the probability that exactly 8 of them favor the building of the police substation will be :-
Hence, the probability that exactly 8 of them favor the building of the police substation = 0.1840
The area of the rectangular roof (both sides of the roof) = 1,360 ft²
Cost to cover both sides = $1,020
<h3>What is the Area of a Rectangle?</h3>
The area of a rectangle = (length)(width)
- Length of one side of the roof = 40 ft
- Width of one side of the roof = √(15² + 8²) = 17
Area of both sides of the roof = 2(area of rectangle) = 2(40×17) = 1,360 ft²
Cost to cover both sides = 1,360 × 0.75 = $1,020

Answer:
30-(-15)-40
=5
Step-by-step explanation:
You will the subtraction sign to open the bracket
30-(-15)-40
when - and - meet it turns to + (note only happens when opening a bracket)
this is ur result....30+15-40=5
thats how u get your 5
