(Since there are no options to chose from, I guess I'll just do my own answer and you'll have to pick the closest one to this one. Or, you could comment the options and I could help you there too.)

Answer:

Yes, the outcomes are likely because there is an equal number of each type of marble.

Step-by-step explanation:

Since there is an equal number of each color of marble, the outcomes of the event are equally likely. If there were more of one marble, it would be unlikely.

For example, if there were 7 blue marbles, 7 red marbles, but there were 8 yellow marbles, then the event would be unequally likely because there were more of the yellow marbles.  So the answer is yes, the outcomes are equally likely.

It would be FANTABULOUS if I could get BRAINLIEST!!!!!!!

Have a great day!! ;p

Suppose that a class contains 15 boys and 30 girls, and that 10 students are to be selected at random for a special assignment.
natka813 [3]
Prob of selected students times prob of selecting boys times prob of selecting 3 boys
total students = 15b + 30g = 45 students

1. 10s/45t = 0.22
2. 15b/45t = 0.33
3. 3b/15b = 0.2

0.22×0.33×0.2=0.0148

1.48%

I'm not sure 100%... double check answer please

A money bag contains ten 5-dollar notes and thirty 10-dollar notes. If a note is randomly selected from the bag, what is the pro
lapo4ka [179]
Not a 5 dollar just means a 10 dollar

probblity=desired outcomes/total possible outcomes


desired=number of 10 dollar notes or 30

total possible=10+30 or 40


the probablity is 30/40 or 3/4 or 75% that you do not select a 5 dollar note

The equation of line / is y=3x/a +5, where a is a positive constant. If the value of a in this equation is doubled, then the res
Anettt [7]

The resulting equation will represent a line whose slope is 1/2 times the slope of the line

<h3>How to determine the slope of the new line?</h3>

The equation of the line is given as:

y = 3x/a + 5

The constant a is a positive constant.

So, when the value of a in the equation is doubled, we have:

y = 3x/2a + 5

A linear equation is represented as

y = mx + b

Where m represents the slope.

So, we have:

m1 = 3/a

m2 = 3/2a

Substitute m1 = 3/a in m2 = 3/2a

m2 = 1/2 * m1

Hence, the resulting equation will represent a line whose slope is 1/2 times the slope of the line
