you choose at random from the letters a,b,c and d and you roll a number cube once. what are the chances that you get an a and 5?

Keith_Richards [23]

1/24 or 4%

There is a total of 24 outcomes
4 letters • 6 numbers = 24 possible outcomes
There are 6 different outcomes when it comes to each letter.
(a1, a2, b1, b2 etc)
so getting a5 is a 1/24 chance because there 24 outcomes and only one of them is a5

7. The claim that started this investigation was that students majoring in engineering are more likely to be in the marching ban

Genrish500 [490]

Answer:

See explanation below.

$P(M|E) > P(M|O)$

Step-by-step explanation:

Notation

First we need to define the following events:

E = The student is in a major of enginnering

O= The student is in a major different from enfinnering

M= The student is in the marching band

Solution for the problem

For this case we can calculate the following probability:

$P(M|E) =\frac{P(M and E)}{P(E)}$

And that represent the following event: "Given a randomly selected student is an engineering major, what is the probability the student is in the marching band"

And the probability that need to calculate to compare is this one:

$P(M|O) =\frac{P(M and O)}{P(O)}$

And that represent the following event: "Given a randomly selected student is NOT an engineering major, what is the probability the student is in the marching band"

And if the claim is satisfied we need to see this:

$P(M|E) > P(M|O)$

Find the measure of the exterior angle.

Rama09 [41]

Step-by-step explanation:

measure of exterior angle = sum of 2 non adjacent angles

4X = 90 + X

3X = go

X=30

exterior angle = 30x 4 =120

marin [14]

An outlier for a data set is a number which stands out, meaning it is not close to the rest of the numbers. It can either be greater OR less than the rest of the numbers.

<span>23, 34, 27, 7, 30, 26, 28, 31, 34

Which number stands out from this data set?

Yep! 7. This is because it is not close to the other numbers, whereas the other numbers are closer to each other.

A) 7.</span>
