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.

Step-by-step explanation:
- Angles around a point sum to 360°
- 1 hour = 60 minutes
Therefore, the minute hand of a clock travels 360° in 60 minutes
Number of degrees the minute hand will travel in 25 minutes:
To find how far the tip of the minute hand travels in 25 minutes, use the Arc Length formula:
Given:
- r = length of minute hand = 14 ft
= 150°
