Question

Janie flips a coin 70 times and records if it comes up heads. If getting heads is a success, what is the probability of a failure?

Answer 1

Well since there are only two sides, the chance of not getting heads 70 times is 1/2 of 70. So do 70/2 or 1/2 * 70 in order to find the answer. Then you can put the answer (x) over 70 and then simplify to 1/2.

Answer 2

so wats that answer

Answer 3

I cannot give you the direct answer. You must work it out for yourself.

Answer 4

i got 35

Answer 5

In order to get the answer, you must find 1/2 of 70 - the probability will be shown as a percent.

Answer 6

So if you divide by two, that means 35 is half of 70

Answer 7

is it 0.2

Answer 8

So the fraction is 1/2

Answer 9

So as a decimal, it is 0.5

Answer 10

It's possible that not all the info given in this problem statement is necessary.
The chances of getting a head is simply 0.5.
What are the chances of getting a tail (not getting a head)?

Please note carefully: 35 is NOT a viable probability. Probabilities are always between 0 and +1.

So that rules out 35 as an answer.

Again: What are the chances of not getting a head?

Answer 11

When creating percents we move the decimal point 2 places to the right

Answer 12

So it is a 50% chance

Answer 13

Chance of what? Please be specific.

Answer 14

Do you understand? Because you need to learn not cheat.

Answer 15

50% chance of not getting a head

Answer 16

ok can you help with this question

Answer 17

Thirty-three percent of all students at a high school like beef stew. Out of 300 students, 40 are selected randomly and asked whether they liked beef stew. If liking beef stew is a success, what is the probability of a failure for this binomial experiment?

Answer 18

40 over 300 times 100. The answer must be subtracted from 300.

Answer 19

i dont get it

Answer 20

Look, sexy, it is important that you are learning and do not just want answers. Do you understand probability or no?

Answer 21

no

Answer 22

Paraphrase the question as follows:
"The probability that a student selected at random at a certain high school likes beef stew is about 1/3 (33.3%). What is the probability that a student selected at random does NOT like beef stew?"

Answer 23

Another way to put this would be: "In a situation in which there are only two possible outcomes to an experiment, the probability of success 1/3. What is the probability of failure in this experiment?"

Answer 24

Okay, um, I am going to leave you in the hands of @mathmale but contact your teacher for more questions or go to Spy Guys 6 - a good math website

Answer 25

i dont know

Answer 26

If P(success) in a binomial experiment is 1/3, then P(failure) is simply 1-1/3 = 2/3.

Answer 27

What specifically do you want to know? If you're not familiar with the terms I'm using, we could look them up on the Internet. it's difficult to respond to "what I dot get".

Answer 28

how to get the answer

Answer 29

In this case, all you really need to know is in what I typed earlier:

"If P(success) in a binomial experiment is 1/3, then P(failure) is simply 1-1/3 = 2/3."

Answer 30

so i have divide the number

Answer 31

Look at the experiment of tossing a fair coin. The coin could land heads up or tails up.
there are only those two possible outcomes.
Because the coin is a fair one, the probability that you'll get a HEAD is 1/2. The probability that you'll get a TAIL is 1-1/2 = 1/2.

In your math problem, there are again only two possible outcomes. If the probability of one outcome is 1/3, then the probability of the other outcome is 1-1/3.
