Question

Luke has a spinner divided into ten equal segments, each with a different color. In fifty spins, he spun yellow ten times. How does this compare to the expected result?

The experiment resulted in 5 more yellows than expected.

The experiment resulted in ten more yellows than expected.

The experiment resulted in 5 fewer yellows than expected.

The experiment resulted in ten fewer yellows than expected.

Answer 1

plz help me somebody

Answer 2

If you have 10 equal segments on the spinner, and only 1 of them is yellow, what is the probability of getting yellow on 1 spin?

Answer 3

1

Answer 4

a probability of 1 means that it is certain: all the probabilities add to 1. Next guess? :-)

Answer 5

3

Answer 6

come on, if 1 is certain, what does 3 represent?

Answer 7

it means un certain......I don't know im bad at math

Answer 8

if you have a multiple choice question with 2 answers, both equally likely, and you guess, what is the probability of getting a correct answer?

Answer 9

50%

Answer 10

or flipping a coin: if I flip a coin right now, and you guess heads or tails, what is the probability that you will be right?

Answer 11

okay, 50%. why 50%?

Answer 12

because theirs only to so you would put it on half

Answer 13

okay. there's 1 favorable outcome, but 2 possible outcomes. The probability of a favorable outcome is

# of favorable outcomes / # of possible outcomes

1/2 = 0.5 or 50%

now, look at that spinner problem again. What do you think the answer should be?

Answer 14

(for what is the probability of getting yellow with 1 spin)

Answer 15

the second one?

Answer 16

no...........? am i wrong

Answer 17

are you still their

Answer 18

how many possible outcomes are there?

Answer 19

10 different colors, each segment the same size...

Answer 20

The answer would be the first one right

Answer 21

by the way, as you've made this mistake a couple of times now, "their" is a possessive, like "those are their homework problems"

to ask if someone or something is still present, "there" is the word you want. "Hello, are you there?"

if you are saying "they are", then you can use "they're", which is a contraction.

Answer 22

No, we're going to work through this, and you won't need to ask me which answer is correct, you'll understand and know which is correct :-)

Answer 23

I know but I have to have the answer right now im in a rush

Answer 24

so, we take 1 spin on that spinner. what is the probability that we get a yellow?

Answer 25

colors are red, blue, green,yellow, orange, purple, magenta, violet, black, white

only 1 is yellow, right? so we have a 1 in 10 chance. on average, if we spin it a large number of times, we should expect about 1/10 of the number to be yellow.

Answer 26

so, let's say that 50 is a large enough number. if we spin 50 times, and we expect about 1/10 of the spins to be yellow, how many yellows is that?

Answer 27

50 * 1/10 = 50/10 = 5, right?

but we got 10 yellows, according to the problem statement, so that is 10 -5 = 5 more than we expected.

Answer 28

oh i get it

Answer 29

thanks for the help

I appreciate that you're in a rush to get an answer, but OpenStudy isn't here to give you answers, it's here to help you learn.

Answer 31

yep

Answer 32

I'm happy to answer questions, but you'll have to work along with me, so be sure to allow plenty of time next time :-)
