Question

You roll a standard number cube once. Find P (0).

Answer 1

A. 7/6
B. 1
C. 1/2
D. 0

Answer 2

So, is P the probability of it landing on 0?

Answer 3

If so, 0 is not on a standard die.

Answer 4

I think so but I am not sure

Answer 5

do you find a 0 on a standard dice?

Answer 6

number cube*

Answer 7

no

Answer 8

What are your chances of rolling 0 if it isn't on there?

Answer 9

oh yay it is d 0

Answer 12

Sure

Answer 13

From a barrel of colored marbles, you randomly select 7 blue, 5 yellow, 8 red, 4 green, and 6 purple marbles.

3. Find the experimental probability of randomly selecting a marble that is not yellow. Write your answer in simplest form

Answer 14

Can you ask new question in a new post?
So that others can help you too if they want :)

Answer 15

lets take that one in this post only :)

Answer 16

ok

Answer 17

how many total marbles are there?

Answer 18

30

Answer 19

How many aren't yellow?

Answer 20

out of that 30, how many are yellow and how many are not?

Answer 21

5 are yellow and 25 are not yellow

Answer 22

So, the probability of picking a marble that isn't yellow is __ out of 30

Answer 23

5/30

Answer 24

No, that's the chance of picking a yellow.

Answer 25

5 yellows out of 30

Answer 26

Probability = favorable number of events/ total number of events

For probability of not selecting a yellow,
favourable event is picking some other marble =25

so that will be your numerator

Answer 27

Read the question closely, it tells you that they need to know how many are NOT yellow.

Answer 28

A. 1/30
B. 5/6
C. 2/15
D. 1/6

Answer 29

we have to wright the answer in simplest form

Answer 30

Ah, then you need to divide the numerator and denominator until they become the smallest and simplest.

Answer 31

first get the probability
numerator = 25, denominator = total = 30

25/30
now try to reduce this.
25 and 30 can be divided by which smallest natural number?

Answer 32

5

Answer 33

then divide both of them by 5 and tell me what you get?

Answer 34

5/6

Answer 35

There you go!

Answer 36

\(\Huge \checkmark \)

Answer 37

so the answer is b 5/6

Answer 38

Yup

Answer 39

thanks soooooooooooooooo much

Answer 40

No problem

Answer 41

welcome sooooooooooooo much :D

Answer 42

Find the experimental probability of randomly selecting a marble that is either green or purple. Write your answer in simplest form
