A red die is tossed and then a green dieis tossed. What is the probability thatthe red die shows a six or the green dieshows a s

mr_godi [17]

Let's call the event of the red die to show a six as event A, and the event of the green die to show a six as event B.

The theoretical probability is defined as the ratio of the number of favourable outcomes to the number of possible outcomes. On both dices, we have 6 possible outcomes(the numbers from 1 to 6), with one favourable outcome(the number 6), therefore, the probabilities of those events are:

$P(A)=P(B)=\frac{1}{6}$

Each roll is independent from each other, then, the probability of both events happening simultaneously is given by their product:

$P(A\:and\:B)=P(A)P(B)$

Using the additive rule of probability, we have the following equation for our problem:

$\begin{gathered} P(A\:or\:B)=P(A)+P(B)-P(A\:and\:B) \\ =P(A)+P(B)-P(A)P(B) \\ =\frac{1}{6}+\frac{1}{6}-\frac{1}{6^2} \\ =\frac{2}{6}-\frac{1}{36} \\ =\frac{12}{36}-\frac{1}{36} \\ =\frac{12-1}{36} \\ =\frac{11}{36} \end{gathered}$

the probability that the red die shows a six or the green die shows a six is 11/36.

Often, variability is most usefully expressed in the same units as the original data. That's what standard deviation (square root of variance) does. In situations where that is the case, the variance is useful only for getting to the value of standard deviation.

Let f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s. Which statement bes

ivolga24 [154]

Answer:

The correct option is (4).

Step-by-step explanation:

The complete question is:

Let f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s. Which statement best describes the meaning of f(275)?

Houses sell on the market for an average of $275,000 and stay on the market an average of 275 days before being sold.
Houses sell for an average of $275,000.
f(275) indicates houses stay on the market an average of 275 days before being sold.
f(275) represents the average number of days houses stay on the market before being sold for $275,000.

Solution:

The function f (p) is defined as the average number of days a house stays on the market before being sold for price p in $1,000s.

The function provided is: f (275)

That is, p = $275,000.

So, the function (275) describes the average number of days a house stays on the market before being sold for price $275,000.

Thus, the correct option is (4).
