For an in-class demonstration, a teacher flips a fair coin 5 times, and each of the 5 times it lands on heads. A student argues

that it's more likely to land on tails on the next flip. What, if anything, is incorrect about the student's logic?
A.
The student's logic is incorrect; since a coin being flipped 5 times is 5 independent events, the probability of the next flip landing on heads is still 1/2.
B.
The student's logic is incorrect; since a coin being flipped 5 times is 5 dependent events, the probability of the next flip landing on heads is still 1/2
C.
There is nothing wrong with the student's logic; because a coin being flipped 5 times is 5 independent events, the probability the next flip will land on heads is affected by the previous outcomes.
D.
There is nothing wrong with the student's logic; because a coin being flipped 5 times is 5 dependent events, the probability the next flip will land on heads is affected by the previous outcomes.

inn [45]

Answer:

1 1/12

Step-by-step explanation:

3/4 + 1/3

Get a common denominator of 12

3/4 * 3/3 = 9/12

1/3 * 4/4 =4/12

9/12 + 4/12

13/12

12/12 + 1/12

Cooper bought a serving platter originally priced at $20 but on sale for 50% off. After 10% sales tax, what was the total cost?
Gelneren [198K]

Answ

$11.00

Step-by-step explanation:

A quick way to do this would be as follows:  1.10 ( 0.50*$20), or $11.00.


0.50($20) gives us the sale price (at half off); that's half of $20, or $10.

The total due is then $10 (item cost) plus $1 (tax), or $11

Anna [14]

Calculation = 20/10

Number of cupcakes Victor makes = 20

He puts them in equal rows:

Each row contains = 10 cupcakes

To know the number of rows he placed the 20 cupcakes,

we would divide 20 by 10

\begin{gathered} \text{Number of rows = }\frac{20}{10} \\ \text{number of rows = 2} \end{gathered}

Calculation = 20/10

The number of rows of cupcakes Victor makes = 2

Astronomers treat the number of stars X in a given volume of space as Poisson random variable. The density of stars in the Milky
cupoosta [38]

Answer:

Explained below.

Step-by-step explanation:

The random variable <em>X</em> is defined as the number of stars in a given volume of space.

X\sim \text{Poisson}\ (\lambda=1)

The probability mass function of <em>X</em> is:

p_{X}(x)=\frac{e^{-\lambda}\lambda^{x}}{x!}

(7)

Compute the probability of exactly two stars in 16 cubic light-years as follows:

P(X=2)=\frac{e^{-1}\times 1^{2}}{2!}=\frac{e^{-1}}{2}=\frac{0.36788}{2}=0.18394\approx 0.184

(8)

Compute the probability of three or more stars in 16 cubic light-years as follows:

P(X\geq 3)=1-P(X

(9)

In 16 cubic light years there is only 1 star.

Then in 1 cubic light years there will be, (1/16) stars.

Then in 4 cubic light years there will be, 4 × (1/16) = (1/4) stars.

(10)

In 16 cubic light years there is only 1 star.

Then in 1 cubic light years there will be, (1/16) stars.

Then in <em>t</em> cubic light years there will be, [<em>t</em> × (1/16)] stars.
