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:
<h2>p = 1</h2>Step-by-step explanation:
Multiply through by the LCM
The LCM for the equation is 5
That's
We have
2 + 5p = 4 + 3p
Group like terms
5p - 3p = 4 - 2
2p = 2
Divide both sides by 2
We have the final answer as
<h3>p = 1</h3>Hope this helps you
