You can draw 2 cards from a deck of 52. Each card is numbered 1 number from the set {4,4,2,2,1,1,1,3}. What is the conditional probability that you will draw 1 first and 4 second?
Answer:
Step-by-step explanation:
Are the outcomes on the two cards independent? Why?
Yes. The events can occur together. No. The probability of drawing a specific second card depends on the identity of the first card. No. The events cannot occur together. Yes. The probability of drawing a specific second card is the same regardless of the identity of the first drawn card.

Step-by-step explanation:
the probability of making one shot is 75% or 0.75 or 3/4.
the probability to make 2 shots is then
3/4 × 3/4 = 9/16 = 0.5625
and so on.
the probability to miss 1 shot is then 25% or 0.25 or 1/4.
the probability to make at least 4 out of 5 shots is the sum of the probability to make all 5 shots plus the probability to make 4 shots.
or the probability to miss 0 plus the probability to miss 1 shot.
anyway, we can go with the positive approach. it seems to be the same complexity as the negative approach.
the probability to make all 5 shots is
(3/4)⁵ = 3⁵/4⁵ = 243 / 1024 = 0.237304688...
the probability to e.g make the first 4 shots and miss the 5th is
(3/4)⁴×1/4 = 3⁴/4⁵ = 81 / 1024 = 0.079101563...
how many possibilities do we have to make 4 out of 5 shots ?
there is no repetition, and the sequence inside the "picked" 4 does not matter, so we need combinations :
C(5,4) = 5! / (4! × (5-4)!) = 5
so, the probability to make exactly 4 out 5 shots is
81/1024 × 5 = 405/1024 = 0.395507813...
and the total probability to make at least 4 shots is
243/1024 + 405/1024 = 648/1024 = 81/128 = 0.6328125
to control,
this plus making exactly 3 plus exactly 2 plus exactly 1 plus none must be the probability 1 (as there is no other possible outcome).
making 3 :
(3/4)³×(1/4)² = 3³/4⁵ = 27/1024
C(5,3) = 5×2 = 10
270/1024
making 2 :
3²/4⁵ = 9/1024
C(5,2) = 5×2 = 10
90/1024
making 1 :
3/1024
C(5,1) = 5
15/1024
making 0 :
1/1024
in sum
(270+90+15+1)/1024 = 376/1024
plus the 648/1024 = 1024/1024 = 1
correct.

180-(82+63)180-14535°Answer:
C) 35°
Step-by-step explanation:
From inspection of the given diagram, it appears that the line segment NOR is the diameter of the circle (where point O is the center).
Angles on a straight line sum to 180°
⇒ ∠NOP + ∠POQ + ∠QOR = 180°
⇒ 82° + ∠POQ + 63° = 180°
⇒ ∠POQ = 180° - 82° - 63°
⇒ ∠POQ = 35°
As an arc measure equals its corresponding central angle measure:
[tex]\sf \implies \overset{\frown}{PQ}= \angle POQ[/tex]
[tex]\sf \implies \overset{\frown}{PQ}=35^{\circ}[/tex]
Please help me geometry proof for trapezoid
A trapezoid is a quadrilateral that has two parallel sides with a height.
The proof for trapezoidFrom the diagram, AK = 1/2(AD-BC)
The combination of the bases of the equilateral triangle and the parallelogram is = the base of the trapezoid.
Therefore, BC = AD - 2AK
Make AK the subject of formula,
AK= 1/2 (AD -BC)
From the second equation given,KD = 1/2(AD - BC). This is wrong because of the following,
BC is parallel to KD.
Therefore length of KD = BC - AK and not KD = 1/2(AD - BC).

1. Suppose a married man and woman both carry the gene for cystic fibrosis but don't
have the disease themselves. According to the laws of genetics, the probability that
any child they have will develop cystic fibrosis is .25.
a) Explain what this probability means.
b) If the couple has 4 children, is one of them guaranteed to have cystic fibrosis.
Answer:
a) Probability is the chance or possibility that an event will occur.
b) No,
just as the question states there is a 25% chance of this event happening in a child, so no matter the number of children they have the chances of them getting cystic fibrosis is 25% for each child and it's never guaranteed.

Answer:
1/8
Step-by-step explanation:
I'd start by rearranging the terms for y:
11x-8y=-1
-8y=-1-11x
y=[tex]\frac{-1-11x}{-8}[/tex]
The x-intercept is found when x equals 0, so substitute 0 for x in this new equation to find the y-intercept:
[tex]y=\frac{-1-11x}{-8} \\y=\frac{-1-11(0)}{-8}\\ y=\frac{-1-0}{-8} \\y=\frac{-1}{-8}\\ y=\frac{1}{8}[/tex]
The y-intercept is 1/8

A colony of 10,710 bacteria doubles in size every 129 minutes. What will the population b
516 minutes from now?
The population after 516 minutes is 171360 bacteria
How to determine the population after 516 minutesFrom the question, we have the following parameters that can be used in our computation:
Initial, a = 10,710 bacteria
Rate = doubles i.e. 2
Using the above as a guide, we have the following:
f(x) = a(2)^x
Where x is the time
516 minutes is 4 times 129 minutes
This means that
x = 516/129 = 4
So the population after 516 minutes can be calculated as follows:
f(4) = 10710 * (2)^4
Evaluate
f(4) = 171360
Hence, the population is 171360
