Question

A bag contains 10 marbles of the same size that are red, yellow, and orange. The probability of picking a red marble is 10%. The probability of picking a yellow marble is 60%. Determine the probability of picking an orange marble from the bag and then classify the probability of picking an orange marble as likely or not likely to occur.

Answer 1

and choices?

Answer 2

I submitted the wrong question. This is what I need help on..
A bag contains 20 marbles of the same size that are blue, green, and red. The probability of picking a blue marble is 20%. The probability of picking a green marble is 50%. Determine the probability of picking a red marble from the bag and then classify the probability of picking a red marble as likely or not likely to occur.

Answer 3

It is a essay question

Answer 4

so the blue r 20% and the green is 50% right?

Answer 5

Yes

Answer 6

how about add them together so 20+50=70 so tha would be 70%

Answer 7

100%-70%=30%

Answer 8

so 30% of the marbles are red

Answer 9

did that help?

Answer 10

Gareth believes that if he flips a coin 820 times, it will land heads up exactly 410 times. What would you tell Gareth about his prediction?

Answer 13

click best response

Answer 14

well if he flipped it 820

Answer 15

so i would say the prediction is....

Answer 16

r there answer choices?

Answer 17

No.. unfortunately

Answer 18

dang......

Answer 19

I think I'm supposed to find the probability.. If that helps

Answer 20

And if it's theoretical and experimental probability

Answer 21

ur right

Answer 22

Okay well I think it's reasonable but is it right or wrong? And what is the difference between theoretical and experimental probability for this?
