Question

When a coin is flipped, there are two possible outcomes: heads or tails. If a coin is flipped three times, what is the probability that there will be tails all three times?

Answer 1

I can post the possible answers if necessary

Answer 2

Don't post possible answers.

Answer 3

OK

Answer 4

The 3 flips are independent trials each with a probability of 1/2 for tails. Probability of 3 tails in a row is
\[\frac{1}{2}\times \frac{1}{2}\times \frac{1}{2}=you\ can\ calculate\]

Answer 5

Figure it out yourself the same we did the previous question.
Write a table with all possible outcomes.
Then see what fraction your desired outcome is of the total number of outcomes.

Answer 6

0.125

Answer 7

Thanks!

Answer 8

You're welcome :)

Answer 9

There are 8 possible outcomes, and only 1 is three tails, so the probabilty of three tails is 1/8
