What is the volume of a sphere with a radius of 1/2
krok68 [10]

Step-by-step explanation:

Volume = \frac{4}{3} \pi r^3

V = \frac{4}{3} \pi (\frac{1}{2} )^3

V=\frac{4}{3}\pi  (\frac{1}{8})

V= 0.5233..

So, the volume of the sphere would be 0.523.

In a recent​ year, an author wrote 169 checks. Use the Poisson distribution to find the probability​ that, on a randomly selecte
grigory [225]
We should first calculate the average number of checks he wrote per day.  To do that, divide 169 by 365 (the number of days in a year) and you get (rounded) 0.463.  This will be λ in our Poisson distribution.  Our formula is
P(X=k)= \frac{ \lambda ^{k}-e^{-\lambda} }{k!}.  We want to evaluate this formula for X≥1, so first we must evaluate our case at k=0.  
P(X=0)= \frac{0.463 ^{0}-e ^{-0.463} }{0!} \\ = \frac{1-e ^{-0.463} }{1} =0.3706
To find P(X≥1), we find 1-P(X<1).  Since the author cannot write a negative number of checks, this means we are finding 1-P(X=0).  Therefore we have 1-0.3706=0.6294.
There is a 63% chance that the author will write a check on any given day in the year.<em />

You have a bag of 12 marbles. Four are blue, 6 are green, 2 are red, and the others are yellow. What is the probability of drawi
8090 [49]

Answer:

Probability = \frac{1}{11}

Step-by-step explanation:

Given

Blue = 4

Green = 6

Red = 2

Total = 12

Required

Determine the probability of drawing red and green without replacement

This is calculated as follows:

Probability = P(Red\ and\ Green)

Probability = P(Red)\ and\ P(Green)

Probability = \frac{n(Red)}{Total} * \frac{n(Green)}{Total - 1}

We used Total - 1 because it's a probability without replacement:

Probability = \frac{2}{12} * \frac{6}{12- 1}

Probability = \frac{2}{12} * \frac{6}{11}

Probability = \frac{1}{6} * \frac{6}{11}

Probability = \frac{1}{11}

<em>Hence, the required probability is 1/11</em>
