The probability of getting two red chips is:
P = 1/21.
How to get the probability?
The probability of getting a red chip is equal to the quotient between the number of red chips and the total number of chips.
There are 4 blue chips and 3 red chips, for a total of 7 chips.
For the first draw, the probability of getting a red one is:
p = 3/7.
For the second draw, now there are 2 red chips and 6 chips in total, so now the probability is:
q = 2/6 = 1/3
Then the joint probability, given by the product between the two individual probabilities, is:
P = q*p = (3/7)*(1/3) = 1/21.

your recipe calls for 2 over 3 cups of sugar. you are only making 2 over 4 of the recipe. how much sugar do you need? not simplified
The quantity of sugar required for 2/4 of the recipe is 1/3 cups
How to solve fraction?let
x = quantity of sugar neededRatio of sugar to recipe
2/3 : 1 = x : 2/4
2/3 ÷ 1 = x ÷ 2/4
2/3 × 1/1 = x × 4/2
2/3 = x × 2
2/3 = 2x
x = 2/3 ÷ 2
x = 2/3 × 1/2

reflection across the y-axis
Answer:
A reflection of a point over the y -axis is shown. The rule for a reflection over the y -axis is (x,y)→(−x,y) .
Step-by-step explanation:
Expand and simplify: (-7y - 8) (y - 4)
To expand an expression, use FOIL method.
F - FirstMultiply the first term in each expression inside the parentheses.-7y and y are the first terms in each expression.
(-7y)(y) = -7y²
O - Outside Next is to multiply the terms outside. (The first term in the first expression and the last term in the second expression)-7y is the first term in the first expression
-4 is the last term of the second expression
(-7y)(-4) = 28y
I - InsideThe next step is to multiply the terms inside. (The last term in the first expression and the first term in the last expression)-8 is the last term in the first expression
y is the first term in the second expression
(-8)(y) = -8y
L - LastLast step is to multiply the last term in each expression.-8 is the last term of the first expression
-4 is the last term of the second expression
(-8)(-4) = 32
Combine all simplified terms.

A drum has a diameter of 20 inches and is 16 inches deep. Find the volume of this drum.
The volume of this drum is approximately
in³.
HELP QUICK!!!!
Answer:
[tex] \boxed{\rm \: Volume_{(Drum)} = 5024 \: in {}^{3} }[/tex]
Step-by-step explanation:
Given :
Diameter of a drum = 20 inchesDeep ( height ) of the drum = 16 inchesπ = 3.14To Find:
The volume of the drum.
Solution:
We all know that drum is cylindrical.So we'll use the formulae of the volume of cylinder,to find its volume.
[tex] \boxed{\rm \: Volume_{(Cylinder)} = \pi{r} {}^{2} h}[/tex]
Where,
r = radiush = height (deep)π = 3.14The value of radius ain't given,but the diameter is given.We can use the formulae of radius.
[tex] \rm \: Radius = D/2[/tex]
D = diameterSubstitute the value of diameter:
[tex] \rm \: Radius = \cfrac{20}{2} = 10[/tex]
Hence,the radius is 10.
So we could now use the formulae of the volume of cylinder:
[tex] \rm \: Volume_{(Cylinder)} = \pi{r} {}^{2} h[/tex]
π = 3.14r =10 inh = 16 in[Firstly bring the answer in terms of π then plug π = 3.14 and then simplify.]
[tex] \rm \: Volume_{(Drum)} = \pi(10) {}^{2} (16)[/tex]
[tex] \rm \: Volume_{(Drum)} =\pi100(16)[/tex]
[tex] \rm \: Volume_{(Drum)} = 1600\pi[/tex]
[tex] \rm \: Volume_{(Drum)} = 1600 \times 3.14[/tex]
[tex] \boxed{\rm \: Volume_{(Cylinder)} = 5024 \: in {}^{3}} [/tex]
Hence, we can conclude that:
The volume of this drum is 5024 in^3.

You play a game that requires rolling a six-sided die and then randomly choosing a colored card from a deck containing 3 red cards, 6 blue cards, and 8 yellow cards. Find the probability that you will roll a 5 on the die and then choose a red card.
The probability of getting a red card and rolling a 5 is = 3/85
How to find the probability?First, we want to find the probability of rolling a 5.
There are 6 outcomes on the six-sided die, so the probability of getting a particular value is:
P = 1/5.
Then, the probability of randomly drawing a red card is given by the quotient between the number of red cards and the total number of cards:
P' = 3/(3 + 6 + 8) = 3/17
The joint probability is given by the product between the individual probabilities:
