Question

Kathy has a coin, what is the probability of flipping three heads in a row? Please choose one answer.

Answer 1

Answer:

About 1/8 of a chance or a 12.5% chance

Step-by-step explanation:

See, we already know that the chance of one head is going to be one-half, right?

So we can multiply that fraction by itself by as many times as the coin is flipped in order to get our probability.

So 1/2*1/2*1/2 = 1/8

1/8 is also equal to the decimal .125, and percentages are based of the number one, so as a percentage it should look like this: 12.5%

To be more in depth with it, let's look at this:

Based off this chart, we can also identify that there is a total of 8 possible outcomes, so it is not a coincidence that there is a 1/8 chance of getting heads 3 times.

Answer 2

Answer and Explanation:

The probability of flipping a coin to get heads is 1/2 or 50%. If you multiply this, by how many times you flip it, or 1/2 * 1/2 * 1/2, then you get 1/8 or 12.5% chance that she will get heads 3 times in a row
